changing the number of times to run foreach

[Jnerocorp]

Ok I am making a form that the user inputs the following:

 

 

URL (input type=text name=url)

HEIGHT (input type=text maxchars=3 name=height)

WIDTH (input type=text maxchars=3 name=width)

Number (input type=text name=number) of times to display per refresh

 

The form will be using GET and processed on the same page

 

That field "Number" is the field that I want to set for the number of times to run foreach OR it will be the number of times to place "URL" into an arrray

 

so if someone puts 5 it will either display URL 5 times or put "URL" in the same array 5 times please let me know if i am explaining this clear enough or not.

Should be a simple loop

ie

for($n=0;$n<$_GET['number'];$n++){

echo $_GET['url']."<BR />/n";

}[/Number ]

[taquitosensei]

if(isset($_POST['number']) && is_int($_POST['number']));

{

for($a=0;$a<$number$a++)

{

// do whatever in your loop

}

}

Ok Neither of those codes are working i am not getting errors though

 

the url i tested it with is this:

http://jnerocorp.com/for.php?url=http://google.com&?number=2

 

 

this is the Code I am using

<?php
if(isset($_GET['number']) && is_int($_GET['number']))  {

$number = $_GET['number'];
$url = $_GET['url'];

for ($i = 0; $i < $number; $i++) {
    echo "$url <br>";
}

}
?>

Can you please click topic solved

is_int() will return false when checking strings (values in URL are strings).  use is_numeric() or ctype_digit() instead.

 

how are you getting it to work with is_int()?

[mrMarcus]

is this the code you are currently using, exactly as seen below:

 

<?php
if(isset($_GET['number']) && is_int($_GET['number']))  {

$number = $_GET['number'];
$url = $_GET['url'];

for ($i = 0; $i < $number; $i++) {
    echo "$url <br>";
}

}
?>

You could also use the array_fill function to create an array of however many of the URLs you want.

 

$urls = array_fill(0, $_GET['number'], $_GET['url']);
