How display custom warning and success message?

[tomasi]

Hi,

Can you please help me?

I would like to display custom message warning and success when people using my form module.

The custom warning message would for example: "You must enter your name"

Thank you in advance ! 

[vekia]

but the question is: where, in back office, front office you want to display this warning / success ?

and after what actions?

[tomasi]

I want display the message like the maintenance message of prestashop in red for warning and in green for success.

 

[vekia]

but where? and after what action? without actions?

This function display error when users don't wrtite in a form:

 

public function displayError($errorList)

  {

$errorString = "";

foreach( $errorList as $key => $value )

{

$errorString .= $value."<br/>";

//$this->hook($params);

 

}

echo '<span class="warning" style="display: block;">'.$errorString.'</span>';

 

  }

 

I want to display $errorString in a custom message warning

[vekia]

still no answer where exactly, it's most important question

[lpbellier]

He probably means after entering your information, right under the field that is missing the info in the form.

You can display success by using                

 

$this->confirmations[] = "Successful message";

 

And error: 

 

$this->errors[] = Tools::displayError("Your error");
