Get all $_POST variables 1

[BiggerBrother]

I ahve a form, with over 50 checkboxes. When the form submits, I need to be able to iterate through all the $_POST varaibles, to create an sql string. I have no idea what these variables will be called, as they are related to the name of theproduct I am searching for.

Is there a way to return all the post variables, without knowing the name of each?

Many thanks,

BB

Here is some code that I use for something similar:

foreach($_POST as $variable => $value)
	echo "\n".'<input type="hidden" name="'.$variable.'" value="'.$value.'"/>';

Cheers,
Jeff

do you need to create a string for each checkbox since a checkbox can have multiple values ?? or just 1 total string?

 

[BabyJeffy]

A checkbox can have one value. You either select the checkbox (and the checkbox name and value are passed into the form collection upon submit) or you de-select it (in which case the name and value for the checkbox are never sent).

More details on HTML can be found in the HTML, XHTML and CSS forum at: forum215.

that's called a radiobutton if it's yes or no.
checkbox is for multiple answers possible

I have a nice script for checkboxes multiple values

How are the checkboxes named? If you show us that code, we might be able to come up with a more effecient way of naming them so that your coding to check them is simple.

If your products are defined in a prefixed order - as in an array - you could send value as an index to that array, and colect the indexes in a new array.
After the submit, run thru the second array reading the indexes to the first array.

I'm doing this and it is working fine.

Sorry, I've been away for a couple of days, and so really bad at answering.

BabyJeffy, thanks, that put me on the right track.

Thanks

Be VERY careful with just putting these variables into a SQL string. There are several ways hackers could make use of this.

See for example:
