if no additional images do this, else do this

[sephiroth]

Hi Guys :)

I'm wondering is there a way to write an if statement something alongs the lines of

if (noadditionalimages == true) {

echo 'no additional images';

} else {

echo 'there are additional images';

} 

so basically if there are no additional images it outputs one thing, and if there are it outputs another

Cheers!

What's wrong with the statement you have written? ok, so the "noadditionalimages" needs to be predefined, or passed as a variable for this to work with PHP, but other than that it seems ok.

You could also use something like

$message = ($noadditionalimages) ? 'no additional images': 'there are additional images';

echo $message ;

Somehow I don't thing this is what you are asking though.

Perhaps you are wondering how to determine whether an additional image exists or not? or is it the logic, or perhaps just the syntax you are having difficulties with?

yes, I'm looking for how to determine if there are additional images...

Using the templates and overrides ... you could customize the file:
tpl_modules_additional_images.php

where it tests for if the number of additional images is greater than 0, then it displays them ... add an ELSE to the IF and you can customize it to output whatever you want ...

Linda has already advised you in regards where you'll need to do your customisations (no sensible person would argue with her)

You will probably find it convenient to use one of zen-carts own functions to perform the actual 'does it exist' check.

The function (located in /functions/general.php) which you should NOT edit. is:

function zen_info_image($image, $alt, $width = '', $height = '')

This is the full function

 function zen_info_image($image, $alt, $width = '', $height = '') {
    if (zen_not_null($image) && (file_exists(DIR_FS_CATALOG_IMAGES . $image)) ) {
      $image = zen_image(DIR_WS_CATALOG_IMAGES . $image, $alt, $width, $height);
    } else {
      $image = TEXT_IMAGE_NONEXISTENT;
    }

    return $image;
  }

Hope you find this useful.

Actually, you do not have to test for anything ... the template has the test with:

 if ($flag_show_product_info_additional_images != 0 && $num_images > 0) {

Just add the ELSE to that IF and what you want to do ...

As someone told me recently, sometimes the most obvious is the best.
