Run the code more than once...

[MrXander]

Hi there,

 

I am trying to get my code running more than once when a user submits their form.

For example, when a user vists the page called "search", then can enter a number between 1 and 100. Once they hit submit, I want the code to run completely, x amount of times, depending on what the user requests.

Can anyone help??

make it a function and use a for loop.

Example? ???

for/while

example

<?php
$num = $_GET['count'];
$i = 1;
while($i<=$num){
//Do some stuff
$i++;
}
?>

you can replace while with for and have all your $i declaration in the naming of the loop i.e

<?php
$num = $_GET['cout'];
for($i=1;$i<=$num;$i++){
//do some stuff
}
?>

Create a form, make it submit to itself (the current page) and use the get as the method. Create a text field called loop and a submit button.

 

Then in your PHP code check to make sure $_GET['loop] exists and that is of a numerical value, using isset and is_numeric within an if statement. If $_GET['loop] variable exists and is of a numerical value use it in your for loop.

 

it really is straight forward. From reading the above you should be able to accomplish what you are trying to do.

Just thought I note that a for construct is a much more rigid system than the while construct.  This is because a for construct must always return true and do the next step (as long as condition B is true $i<=$num)  however in a while construct you can use logic to test if $i should advance or not such as if($i%2 = 0 ) {$i++;} else{$i=$i;}

 

both have advantages, but in general I'd use a while loop for most things because it just makes more sense.
