PHP Form Input

Expand Post »

Right first of all i'm new to php and i know that this is simple, but i just can't figure it out...

1st, I set up a php site that on the first page it has a textbox, lets say its name is text1...

I set up the sql so that the value of text1 was a criteria to serch for in the title record of the database...

Now the 1st page of results are correct but the next are wrong because the value of text1 is gone...

i've tried this:

echo "<input type='hidden' name='hiddenField' value = '";
echo $_REQUEST['festname'];
echo "'>";

and this:

echo "<input type='hidden' name='hiddenField' value = '";
echo $festname;
echo "'>";

will someone help me please, i will be very grateful....

Re: PHP Form Input

The best way to go about this is to keep a URL variable as you're going through the pages. So anywhere you create the link to go to the next page or back, include a variable of the search term. So something like this:

PHP Syntax (Toggle Plain Text)

 
search.php?query=ninjas

Then, all you have to do to retrieve it is:

PHP Syntax (Toggle Plain Text)
 
$_GET['query']
 
$_GET['query']

So for your code, it'd be something like this:
[php]
echo "<input type='hidden' name='hiddenField' value = '";
echo $_GET['query'];
echo "'>";
[/php]

Also, when passing variables around through the URL, always consinder SQL Injections. Click here for more info:
