Hmm… code looks very familiar ;)

Yup. It’s based upon zem_contact_reborn. A client specifically asked me to add the form functionality from that plugin in to mem_moderation. The first time I typed the post above mentioned that, but the site ate the post.

Very nice! I haven’t had a chance to play around with it yet, but sounds like something that would cut development time on several plugins.

Just thought of a new plugin based on this. Should be simple but a form to db plugin. Let admins create new tables in the backend to store data from a form.

Cool. I’m currently adding the tag, mem_form_file so I can migrate mem_moderation_image.

Typolight has something like this:

This will give me a chance to develop on my jquery skills as well.

Let me know if there are any mem_form features that would assist you towards completing that plugin.

Hi, I’m trying to put together a slightly modified registration form which collects some addtional data for equal opportunities compliance purposes which needs inserting into a separate table.

I’d like to be able to populate some select and checkbox fields automatically by selecting values from the database. However because any PHP in my form isn’t processed until the 2nd pass, if I do something like

<txp:php> foreach (thingFromDatabase as thing) { echo “<txp:mem_form_checkbox attrs />”; }
</txp:php>

the checkbox gets created in the output HTML, but isn’t processed by the plugin to ‘save’ the values from the posted form. Hence they aren’t available in $mem_form_values[].

Does anyone know if there is any magic that can resolve this, or might I either have to make the fields static, or access the $_POST variables directly?

Manfre · 2008-02-26 18:10:32

Don’t use inlined php. Instead, create a plugin and have it hook in to submit and default events as described in the plugin help. You are then left with the option of hooking the display event to add the checkboxes, or you can use <txp:mem_form_check …> in the form.

Thanks Michael,

hooking into the submit callback is obviously where I should be acting on the data. Cheers for pointing me in the right direction, I think I’ve got a handle on that now.

Am I right in thinking that with the display event I can add HTML to the form at either the beginning or the end, based on the $pre value? Is there any way of replacing a tag on a page from within a callback in Texttpattern? Ie. can I put something in the middle of the form and have the callback replace that with something else?

Also, am I right that using the callback to programmatically add fields, I still can’t add <txp:mem_form…> tags and pull out the data from the $mem_form_values[] array? As they’re not procecced I’ll still have to work with $_POST to get the values from the extra fields I add? That seems to be the result I get if I add mem_form tags from my display callback.

Cheers for your help,
Alex

By making plugin & function ;) tags are always replaced with functions (or custom parser with plugin).

$_POST to get the values from the extra fields I add? That seems to be the result I get if I add mem_form tags from my display callback.

With plugin you can get them easily, in example with ps('name_of_the_field'); or extract(psa('name1','name2')); or by just calling the function as Manfre said.
