Multiple values in database field - php

Question

I have a specifications table for some products. Some products come in different colors. So to make that clear it shows some little color boxes.
So I have table field colors which stores colors like this:
black,white,green
I came this far with the code:
<?php
foreach($result as $kleur) {
$myString = $kleur['kleur'];
$myArray = explode(',', $myString);
print_r($myArray);
?>
<tr>
<td width="20%">Kleur:</td>
<td>
<div class="item">
<img src="http://www.ledframes.nl/images/product_details/accessoires/kleuren/<?php echo $myArray[0];?>.jpg"/></a>
</div>
</td>
</tr>
<?php
}
?>
The print_r shows all the values from the field. And if the change the number at echo $myArray[0] it shows the right color boxes in my specifications table.
Now my question is, if the color field has multiple values how do I loop it so it shows all the color blocks?
I read somewhere that you can use something like this:
foreach( $array as $name => $key)
I have tried to implement this to my code but can't get it to work

Answer 1

If I understand your problem correctly, $result is the array of database records, and for each record (which you call $kleur), $myArray is the array of color names.
So, to show all the color fields, you need another loop over $myArray, e.g. like this:
<?php
foreach($result as $kleur) {
$myString = $kleur['kleur'];
$myArray = explode(',', $myString);
print_r($myArray);
?>
<tr>
<td width="20%">Kleur:</td>
<td>
<?php
foreach($myArray as $colorName) {
?>
<div class="item">
<img src="http://www.ledframes.nl/images/product_details/accessoires/kleuren/<?php echo $colorName;?>.jpg"/></a>
</div>
<?php
}
?>
</td>
</tr>
<?php
}
?>
