How to go throught custom_field as an array and write up a list?

beztak · 2006-04-05 10:48:39

I have for example custom field in which I’ve got this: g,x,f,c

I need to read this content as an array (maybe not – I’m not PHP coder) and then in article form (or inside the plugin) to display this:

<code><ul>
<li class=“g”>Sometext for g</li>
<li class=“x”>Sometext for x</li>
<li class=“f”>Sometext for f</li>
<li class=“c”>Sometext for c</li>
</ul></code>

So I need to read one custom_field values separeted with comma and then write up a UL LI list where the values form custom fields become a class for particular LI. And of course the values I can whenever change so in new article could be there e.g. f,h,s. That’s why I think it must be an array… Text inside particular LI could be changed inside plugin…

Could someone help?

For use within an article form (would go in a <txp:php>...</txp:php> block):

global $thisarticle;
$vals = explode(',',$thisarticle['custom_1']);
echo "<ul>";
foreach ($vals as $line) {
echo "<li class=\"$line\">Sometext for $line</li>";
}
echo "</ul>";

This is untested and off the top of my head, but it should work. I’m not exactly sure what is intended for the text inside each <li>; let me know if this is what you intended or not. Also, the custom field number would need to be changed as appropriate.

Hi KurtRaschke,

your code look very easy, but doesn’t work. Mistake is right at the bigenning because when I add echo $vals; it’s empty. Syntaxe is probably ok, but maybe we need to call $thisarticle in another way. Now it returns:

<code><ul>
<li class=”“>Sometext for </li>
</ul>
</code>
<code> </code>
Could you fix it?

I tested it and the code does work, you just need to make sure that $thisarticle['custom_1'] is using the name you gave the first custom_field. So if your first custom_field name is “stuff” (very creative, I know) then you would want to change the code to reflect that, with $vals = explode(',',$thisarticle['stuff']);.

Check admin » preferences » Advanced preferences for the correct name.

Yes, whatbrick, you’re right. I tried it before as you described, but I made mistake, so I didn’t notice that it works as I need. Now it works perfectly.

Thanks to all for you contribution. I appreciate it.

When my work will be finished on a new site, I will show you to see how much you helped me… (Now I don’t want to be index my site…)

Best Regards,

So the custom fields get populated in $thisarticle by name and not number, eh? I’ll have to remember that for the future—I don’t ordinarily use the custom fields.

Glad to see the code works as intended.
