[SOLVED] check if file_exists - manufacturer's logo

[Jaguaro]

Good afternoon,

I've inserted two lines of code on the manufacturer.tpl file, to display the logo on the manuf.'s page.

 

I would like to error check it, because I have a few manufacturers without logo.

Here is my code:

{assign var="myfile" value="{$base_dir}img/m/{$manufacturer->id}.jpg"}
<img src="{$base_dir}img/m/{$manufacturer->id}.jpg" /> <br/>

I would like to display it only if  the file exists.

 

I tried this, but it doesn't work:

{assign var="myfile" value="{$base_dir}img/m/{$manufacturer->id}.jpg"}
<if file_exist($myfile)>
<img src="{$base_dir}img/m/{$manufacturer->id}.jpg" /> <br/>
</if>

How can I fix it?

 

Thanks,

C

smarty use brackets, not <> so your code will not work

{if file_exists('../path/to/file.jpg')} 
... 
{/if}

Thank you Vekia,
Anyway I wrote the wrong code up here, I know that it requires brackets.

 

After long troubleshooting I understood that my server ( Aruba ) doesn't accept the absolute path for the file_exists function. The code below works because it's with relative path.

{assign var="myfile" value="img/m/{$manufacturer->id}.jpg"}
{if file_exists($myfile)} 
<img src="{$base_dir}img/m/{$manufacturer->id}-large_default.jpg" /> <br/>
{/if}

 

Thanks!

Hi,

Sorry for the late response. But for other members with the same problem, using a relative path is not a good idea.

$base_dir is not the full path but the path on your URL. You need to use _PS_IMG_DIR_.

Assign the variable on your module / controller

 514         $this->smarty->smarty->assign(
 515             'rm_img_dir',
 516             _PS_IMG_DIR_
 517         ); 

On your template, create the var with the fullpath

{assign var="icon_full_path" value="{$rm_img_dir}rm/c{$subcategory->id}.png"}

And use it on your template :

{if file_exists($icon_full_path)}...{/if}

 

Best regards,
