[SOLVED] dynamic name $_POST

[bobohob]

I want to retrieve these value via "for" loop :

 

$_POST['something_1']

$_POST['something_2']

$_POST['something_3']

$_POST['something_4']

$_POST['something_5']

 

How to do this ?

Hello

thanks.

 

but it doesn't work.  the "something" is not array.

If you just copies naveebbj script and not learned how it work it wouldn't of worked. If you have studies for loops you would of spotted the problem. It should be

 

for($i=1;$i<=5;$i++)
{
echo $_POST['something[$i]'];
}

well seeing what you want you should use a foreach loop

 

foreach ($_POST as $strKey =>$strValue)
{
   if (preg_match("/^something\_\d+/",$strKey))
   {
  echo "$strkey - $strValue";
}
}

try

for($i=1;$i<=5;$i++)
{
echo $_POST["something_$i"];
}

Thank you all.

 

for($i=1;$i<=5;$i++)
{
echo $_POST["something_$i"];
}

 

it works.

just a thought, if you don't care about order make it an array
i.e
page 1
[code]
<?php
for ($i = 1; $i <= 10; $i++) {
   echo "<input type=\"text\" name=\"data[]\" value=\"\" />";
}
?>

page 2

<?php

if(is_array($_POST['data'])){

  foreach($_POST['data'] as $value){

        //work on the data

  }

}

?>

[/code]

 

save you a lot of hassle about caring about the array's size
