Custom ALT text in extra field images was created by Tim

Currently an image extra field gets the ALT text from the field label. I'm trying to find a way to customise the ALT text - either taking the item title or potentially the value of another extra field called "ALT Text".

This article (getk2.org/documentation/tips-a-tricks/1129-extra-field-image-type-as-link) about converting the output into a hyperlink gets me close, but I can't quite get it to work for this purpose.

Currently my code to insert the field is just

<?php echo $this->item->extraFields->GALLERYIMAGE->value; ?>

in my item.php override

Which results in:

<img alt="Gallery Image" src="/images/gallery/basketball_profile.jpg">

Thanks in advance for any help.

You can try this..

<?php
        $string = $this->item->extraFields->GALLERYIMAGE->value;
        preg_match('/<img(.*)src(.*)=(.*)"(.*)"/U', $string, $result);
        $imgsrc = array_pop($result);
        ?>

<img src="<?php echo $imgsrc ?>" alt="<?php echo $this->item->title; ?>" />

It will use the item title as alt

That's a great solution Kannan, and easily interchangeable for inserting another extra field as the ALT text instead. It also works fine in a module override with the simple switch of

<?php
        $string = $this->item->extraFields->GALLERYIMAGE->value;
        preg_match('/<img(.*)src(.*)=(.*)"(.*)"/U', $string, $result);
        $imgsrc = array_pop($result);
        ?> 
<img src="<?php echo $imgsrc ?>" alt="<?php echo $this->item->title; ?>" />

with

<?php
	$string = $item->extraFields->GALLERYIMAGE->value;
	preg_match('/<img(.*)src(.*)=(.*)"(.*)"/U', $string, $result);
	$imgsrc = array_pop($result);
	?>
	<img src="<?php echo $imgsrc ?>" alt="<?php echo $item->title; ?>" />

Many thanks - much appreciated!!
