How to looping on module .tpl file

[SOAMJENA]

I am new at Prestashop Module development.

 

I am able to create a new module by going through the module development  tutorial.

 

I am also able to pass values from backend and also displaying it on frontend.

 

Now i want to pass a comma or enter separated values from a textarea field on admin panel and displaying it through looping on module .tpl file.

 

But I am unable to loop it on module .tpl file.

 

 

Can you please help me..

 

[vekia]

can you show an example of textarea field contents + your foreach loop please?

[SOAMJENA]

can you show an example of textarea field contents + your foreach loop please?

array(

                'type' => 'textarea',

                'label' => $this->l('Sample Message'),

                'name' => 'MYMODULE_TEXT',

                'size' => 20,

                'required' => false

            ),

 

1. Above is the code on modules/mymodule/mymodule.php for a textarea field on module backend..

 

2. And I pass a comma separated entry on backend e.g (Content1, Content2, Content3) throgh the varibale $my_module_message

 

3. I want to separate above comma separated string (Which is coming through variable $my_module_message) by looping on modules/mymodule/mymodule.tpl file..

 

Can you please help me which loop is essential on smarty tpl file because (Php for loop and explode function does not work.) 

 

Please provide me the right syntax..

[vekia]

why not to explode it with php, then pass variable (array) to smarty array

then you will be able to do on this variable foreach loop

[SOAMJENA]

Can you please provide me the explode function and foreach loop example (partial code) which is to be used on mymodule.tpl file for separating the variable mention on previous comment.

[vekia]

php code:

$string="value1,value2,value3,value4,value5,value6";
$array=explode(",",$string);

//now it's time to pass $array to smarty as myArray variable:
this->context->smarty->assign('myArray',$array);

in template file:

{foreach $myArray as $item}
{$item}<br/>
{foreach}

as a resut you will see:

value1<br/>
value2<br/>
value3<br/>
value4<br/>
value5<br/>
value6<br/>

 

[SOAMJENA]

Hi,

 

 

And Template File mymodule.tpl file code (partial)

 

<?php 

$string="value1,value2,value3,value4,value5,value6";

$array=explode(",",$string);

?>

//now it's time to pass $array to smarty as myArray variable:

$this->context->smarty->assign('myArray',$array);

{foreach $myArray as $item}

{$item}<br/>

{/foreach}

 

But it output the below error on Prestashop frontend (where module is activated) and page is blank.

 

//now it's time to pass $array to smarty as myArray variable: $this->context->smarty->assign('myArray',$array);

 Undefined index: myArray (C:\wamp\www\prestashop\cache\smarty\compile\02\32\e0\0232e0d5e05ec048f66eb5cf084e7071c2fe8ec2.file.mymodule.tpl.php, line 55)

 

 

[SOAMJENA]

<?php 

$string="value1,value2,value3,value4,value5,value6";

$array=explode(",",$string);

?>

 

In which file this code to be placed mymodule.php or mymodule.tpl????

 

If I placed that on mymodule.tpl file then it just comment out on fronted. No output results.

[vekia]

you cant use <?php ?> code in smarty template file

you have to use this code in controller (php file)

[SOAMJENA]

Now I pass varible on mymodule.php

 

My mymodule.php code(partial)

 

public function hookDisplayLeftColumn($params)

{

  $this->context->smarty->assign(

      array(

          'my_module_name1' => Configuration::get('MYMODULE_NAME'),

          'my_module_link' => Configuration::get('MYMODULE_LINK'),

 'my_module_message' => Configuration::get('MYMODULE_TEXT')

      )

  );

  $string="".$my_module_name1."";

$array1=explode(",",$string);

$this->context->smarty->assign('myArray',$array1);

  return $this->display(__FILE__, 'mymodule.tpl');

}

   

public function hookDisplayRightColumn($params)

{

  return $this->hookDisplayLeftColumn($params);

}

public function hookDisplayHome($params)

{

 

  $this->context->smarty->assign(

      array(

          'my_module_name1' => Configuration::get('MYMODULE_NAME'),

          'my_module_link' => Configuration::get('MYMODULE_LINK'),

 'my_module_message' => Configuration::get('MYMODULE_TEXT')

      )

  );

$string="".$my_module_name1."";

$array1=explode(",",$string);

$this->context->smarty->assign('myArray',$array1);

  return $this->display(__FILE__, 'mymodule.tpl');

}

 

 

 It returns below error on backend..

 

 Undefined variable: my_module_name1 (C:\wamp\www\prestashop\modules\mymodule\mymodule.php, line 52)

[vekia]

this variable doesn't exist. define it first before

$string="".$my_module_name1."";

[SOAMJENA]

Hi,

Now My mymodule.php code (partial code)

 

public function hookDisplayLeftColumn($params)

{

  $this->context->smarty->assign(

      array(

          'my_module_name1' => Configuration::get('MYMODULE_NAME'),

          'my_module_link' => Configuration::get('MYMODULE_LINK'),

 'my_module_message' => Configuration::get('MYMODULE_TEXT')

      )

  );

$my_module_message = strval(Tools::getValue('MYMODULE_TEXT'));

$string="".$my_module_message."";

$array1=explode(",",$string);

$this->context->smarty->assign('myArray',$array1);

  return $this->display(__FILE__, 'mymodule.tpl');

}

   

public function hookDisplayRightColumn($params)

{

  return $this->hookDisplayLeftColumn($params);

}

public function hookDisplayHome($params)

{

  $this->context->smarty->assign(

      array(

          'my_module_name1' => Configuration::get('MYMODULE_NAME'),

          'my_module_link' => Configuration::get('MYMODULE_LINK'),

 'my_module_message' => Configuration::get('MYMODULE_TEXT')

      )

  );

 

$my_module_message = strval(Tools::getValue('MYMODULE_TEXT'));

$string="".$my_module_message."";

$array1=explode(",",$string);

$this->context->smarty->assign('myArray',$array1);

 

  return $this->display(__FILE__, 'mymodule.tpl');

}

 

 

And my template file (mymodule.tpl code partial)

 

{foreach $myArray as $item}

{$item}<br/>

{/foreach}

 

But it gives no output on frontend.

 

I can't understand where is the wrong...

 

Please help me.

 

Below also atached my mymodule.php file

 

mymodule.php

[vekia]

where you've got this: "MYMODULE_TEXT" ?, regarding to the: strval(Tools::getValue('MYMODULE_TEXT'));

it is posted somewhere?

[SOAMJENA]

$my_module_message = strval(Tools::getValue('MYMODULE_TEXT'));

 

I use this line to get the value from module back end parameter.

 

http://doc.prestashop.com/display/PS14/Creating+a+PrestaShop+module

 

I follow above Prestashop Module Development Tutorial.

[vekia]

Tools::getValue('MYMODULE_TEXT')

this code returns a value from POST or from GET variable

you form must be posted, or variable must be included to $_GET array.

[SOAMJENA]

Ya..

 

The form is submitted..

 

$my_module_message = strval(Tools::getValue('MYMODULE_TEXT'));

Here  attached the mymodule.php file.

Below is the code for mymodule.tpl file.

<!-- Block mymodule -->

<div id="mymodule_block_left" class="block">

  <h4>Welcome!</h4>

  <div class="block_content">

    <p>Hello,

       {if isset($my_module_name1) && $my_module_name1}

           {$my_module_name1}

       {else}

           World

       {/if}

       !       

    </p>

 

{foreach $myArray as $item}

{$item}<br/>

{/foreach}

<ul>

      <li><a href="{$my_module_link}" title="Click this link">Click me!</a></li>

    </ul>

  </div>

</div>

<!-- /Block mymodule -->

 

please give a look on my attached mymodule.php file..

 

I don't understand where I am wrong..

 

Because I follow everything you mention on earlier comments.

 

but still this time no result output.

mymodule.php

Edited March 4, 2014 by SOAMJENA (see edit history)

[SOAMJENA]

I think there is a problem on my mymodule.php file.

 

I can't able to define the varibale 

 

$my_module_message = strval(Tools::getValue('MYMODULE_TEXT'));

 

in the right position which fetch value (comma separated) from backend.

 

Please advice me or make changes on my mymodule.php file which I sent on previous comment and send it here.

 

So I can understand the syntax and utilize that.

[vekia]

i already said it 

 

Tools::getValue('MYMODULE_TEXT')

this code returns a value from POST or from GET variable

you form must be posted, or variable must be included to $_GET array.

[SOAMJENA]

I understand that

 

 Tools::getValue('MYMODULE_TEXT')

this code returns a value from POST or from GET variable

 

But I am unable to pass that variable through submit..

Please give a look on my mymodule.php file which I send on previous comment.

And advice me where I am wrong and what to do to get that. 

 

Please provide me correct full mymodule.php file code with example how to pass  $my_module_message = strval(Tools::getValue('MYMODULE_TEXT'));

that varible with form submission and explode it through..

[SOAMJENA]

This time my mymodule.php code

 

public function hookDisplayHome($params)

{

  $this->context->smarty->assign(

      array(

          'my_module_name1' => Configuration::get('MYMODULE_NAME'),

          'my_module_link' => Configuration::get('MYMODULE_LINK'),

 'my_module_message' => Configuration::get('MYMODULE_TEXT')

      )

  );

  if (Tools::isSubmit('submit'.$this->name))

    {

$my_module_message = strval(Tools::getValue('MYMODULE_TEXT'));

}

  $string="".$my_module_message."";

        $array1=explode(",",$string);

        $this->context->smarty->assign('myArray',$array1);

 return $this->display(__FILE__, 'mymodule.tpl');

}

 

I pass that $my_module_message = strval(Tools::getValue('MYMODULE_TEXT'));

 

through form submission still no output result. 

[vekia]

and where you've got this form?

please show code of it

[SOAMJENA]

Here is my entire mymodule.php code

 

Please guide me where i am wrong.

 

I can't able to print $my_module_message = strval(Tools::getValue('MYMODULE_TEXT'));

[vekia]

it's a php file, not module template (.tpl) file

[SOAMJENA]

Here is the module template file code (mymodule.tpl file)

 

<!-- Block mymodule -->

<div id="mymodule_block_left" class="block">

  <h4>Welcome!</h4>

  <div class="block_content">

    <p>Hello,

       {if isset($my_module_name1) && $my_module_name1}

           {$my_module_name1}

       {else}

           World

       {/if}

       !       

    </p>

 

{foreach $myArray as $item}

{$item}<br/>

{/foreach}

 

    {$my_module_message}

 

 

    <ul>

      <li><a href="{$my_module_link}" title="Click this link">Click me!</a></li>

    </ul>

  </div>

</div>

<!-- /Block mymodule -->

[vekia]

there is no <form> so variable isn't posted to your hook.

this is why it doesnt work. as i said several times before Tools::getValue uses $_POST and $_GET variables

[SOAMJENA]

Is there any other way to pass a dynamic variable (which contains the value form admin module area) through hook.

 

 

Can you please provide a short example or code how to do that.

[vekia]

let's clarify

 

take alook, you use this code:
 

public function hookDisplayHome($params)
{
  $this->context->smarty->assign(
      array(
          'my_module_name1' => Configuration::get('MYMODULE_NAME'),
          'my_module_link' => Configuration::get('MYMODULE_LINK'),
 'my_module_message' => Configuration::get('MYMODULE_TEXT')
      )
  );
  if (Tools::isSubmit('submit'.$this->name))
    {
$my_module_message = strval(Tools::getValue('MYMODULE_TEXT'));
}
  $string="".$my_module_message."";
        $array1=explode(",",$string);
        $this->context->smarty->assign('myArray',$array1);
 return $this->display(__FILE__, 'mymodule.tpl');
}

it's a Hook function, this part of code is only "executed" when you're browsing front office of your store.

inside function you've got this code:

if (Tools::isSubmit('submit'.$this->name)){
$my_module_message = strval(Tools::getValue('MYMODULE_TEXT'));
}

it is executed only in you will SUBMIT form from front office, in addition variable: strval(Tools::getValue('MYMODULE_TEXT')); must be also submitted because as i said before Tools::getValue functins gets variables from $_GET / $_PARAM variables.

 

what to do?

you have to change it a bit, if you store somewhere contents of $my_module_message you have to use Configuration::get(); function (if you store it in configuration table)

[SOAMJENA]

Thanks now i got it.

 

public function hookDisplayHome($params)

{

  $this->context->smarty->assign(

      array(

          'my_module_name1' => Configuration::get('MYMODULE_NAME'),

          'my_module_link' => Configuration::get('MYMODULE_LINK'),

 'my_module_message' => Configuration::get('MYMODULE_TEXT')

      )

  );

 

$my_module_message = Configuration::get('MYMODULE_TEXT');

 

  $string="".$my_module_message."";

        $array1=explode(",",$string);

        $this->context->smarty->assign('myArray',$array1);

 return $this->display(__FILE__, 'mymodule.tpl');

}

 

This code works for me..

 

Thank You Again...
