PHP - How Can I Add Various Checkboxes To My Form Fillout Page ?

hello all,

im wondering if it is possible to have multiple check boxes that get created based on the number of rows in a table (one representing each row) Code: [Select]
<input type='checkbox' name='approve[$tid]' value='ON'>
and then have a submit button at the bottom of the page that will find all of the checkboxes (it could be 1, or 100) and submit it to my form handling page.

thanks

I built a series of insertion forms to put entries into a mysql database. Everything is working fine, except that I just now realized my checkboxes don't put any entry in. It's just leaving it's respective smallint field as a default "0". Being new, I've must've overlooked how to handle these.

The form's checkboxes have a bit of code in the value that remembers what users chose in case they have to backtrack and redo their form. How would I solve the problem and keep this code? Here's what all the checkboxes are written like:

Code: [Select]
<input type="checkbox" name="green_leaf" value="<?php if(isset($_POST['1'])) echo $_POST['1']; ?>" > green

Hello!

Everything on this form emails the way it should except for the checkboxes. The email simply states "Array" instead of what services are checked off. I don't understand PHP that well so I used a contact form and tried to modify it to include the checkboxes. Didn't work out Please help.

I keep getting the warning "unable to send"   and yet I use everything in the for correctly.   Please help me out.  I have spent hours looking for an answer.   It also posts the checkboxes I select at the bottom. I just want to be sent to the email, not necessarily echoed so I can view it.   Thanks

So I've been scanning forms with checkboxes the same way for years and I can't help but think there's a better way. Sometimes when testing, it get caught in infinite loops the way I do it because basically I'll have it like so:

formpage.php
Code: [Select]
<form action=processform.php>
a1 <input type=hidden name=id value='1'> <input type=checkbox name=a1>
<br>
a2 <input type=hidden name=id value='2'> <input type=checkbox name=a2>
// etc etc for all checkboxes and then,
<input type=hidden name=tracker value='-1000'>
<input type=submit value='Submit'>
</form>

processform.php
Code: [Select]
while(current($_POST) != '-1000')
{

// do stuff with current($_POST) to check the id and the value of the $_POST after it and then call next($_POST) to go to the next line

}


The reason I do this is because if a user clicks the a1 box, there is a value in the $_POST['a1'], but all boxes that are not checked do not pass through a variable. There must be a better way to do this
