DISPLAYING 'AVAILABLE COLORS" IMAGES ON A DETAIL PAGE IF COLOR IS CHECKED IN A LIST FIELD - Jul 25th, 2013
|
In a simple store scenario was trying to display images on a detail page for all colors that are checked as being
available for a particular item.
This was my approach:
First I created an array ($colors1) which contains a comma separated list of all of the colors that are available for
the item.
Next I uploaded images representing all of the available colors in a multi-image upload field and entered the color of
the image in the info1 field for each image.
Then in a foreach loop, I used the strpos function to determine if the info1 value exists in the $colors1 variable and
if it does, display that thumbnail image.
Problem was, the image corresponding to the first color in the $colors1 variable was always skipped, and I couldn’t
figure out why.
Greg Thomas from Interactive Tools postulated that it might be because the first item in the array doesn't have a
leading comma and space, and so as far as the strpos function is concerned it’s not an exact match.
He suggested using the in_array function instead to detect if the color has been selected (was in the array) or not.
Yes, the order of the variables in the 2 functions are opposite from each other, but that’s just the way they need to
be to work.
Here’s the recipe that came out of the discussion:
<table align= “center”>
<tr>
<td colspan="2">
<?php $colors1 = join(', ', $store_inventoryRecord['colors:labels']); ?>
<span class="navigation_font">Available Colors: <?php echo $colors1 ?></span><br />
</td>
</tr>
<tr>
<?php foreach ($store_inventoryRecord['image'] as $upload): ?>
<?php $info1 = $upload['info1'] ?>
<?php // if(strpos($colors1, $info1)): // this doesn’t work?>
<?php if(in_array($info1,$store_inventoryRecord['colors:labels'])): // This works ?>
<td align="center">
<span class="sub_heading_font"><?php echo $upload['info1'] ?></span><br />
<img src="<?php echo $upload['thumbUrlPath'] ?>" width="<?php echo $upload['thumbWidth'] ?>" height="<?php echo
$upload['thumbHeight'] ?>" alt="" />
</td>
<?php endif ?>
<?PHP $maxCols=2; if (@++$count % $maxCols == 0): ?></tr><tr><?PHP endif; ?>
<?php endforeach ?>
</tr>
</table>
