Form data!

[connor4312]

Hi,

I have a list of posts generated from a mysql database with checkboxes whose name is their corresponding post's ID, and using those checkboxes one should be able to delete the posts.

I've tried

print_r($_POST['todelete']);
         
        foreach($_POST['todelete'] as $key => $my_var) {
            printf("Key #%d has the value <strong>%s</strong>", $key, $my_var);
        } 

But that only shows the checks that are on, like:

Key #0 has the value onKey #1 has the value onKey #2 has the value onKey #3 has the value on

So, I'm basically asking how to retrieve the data from all form elements, checkboxes, regardless if they are on or off.

Can you show your form's html markup?

<input type='checkbox' name='todelete[]'>

All entries are ordered, so I can match up which ones are being deleted.

okay:

you will never get "off" checkboxes to show up. they're just not supposed to.

two possible solutions:

1) number your checkboxes. I think this is the quickest, most straightforward solution. this way, it's easy to see which item the checkbox belongs to.

<input type="checkbox" name="todelete[1]">
<input type="checkbox" name="todelete[2]">
<!--etc.-->

2) use radios instead. that way, you'll get a "yes" or "no" value for each item. However, you'll need two buttons for each item, and I <i>think</i> you might need to index them anyway; or your yes/no counts might get confused.

<input type="radio" name="todelete[1]" value="yes"> Delete
<input type="radio" name="todelete[1]" value="no"> Keep
