That doesn't make sense. Are you trying something like this?

 

<?php

if(isset($_POST['submit'])){

for($i=0; $i<count($_POST['a']); $i++){

	echo $_POST['a'][$i]."<br />";
}

}

?>

when using dealing with arrays you want to use foreach loops as they are more effective at moving through arrays but your code should be like this

<?php
if(isset($_POST['submit'])){
foreach($_POST['a'] as $b){
	echo $b;
}
}
?>

 

Scott.

[redarrow]

this worked

 

<?php

if(isset($_POST['submit'])){

foreach($_POST['a'] as $b){

	echo $b;
}

}

?>

why dosent this work please........

 

<?php session_start();

if(isset($_POST['submit'])){

foreach($_POST['a'] as $b){

	$_SESSION['a']=$b[0];

	$_SESSION['b']=$b[1];

	$_SESSION['c']=$b[2];

	echo $_SESSION['a'];
}

}

?>

how comes i can not set  sessions form an array form!

 

example below.........

[trq]

Can you actually describe your problem?

 

Ive said it before but you really ought read the 'howto ask?' link in my signiture.

[redarrow]

only the ecohed session should be echoed but i can echo them all....

 

im try to set sessions from a arrayed form....

 

 

the form is at the first post set to name a[]

 

<?php session_start();

if(isset($_POST['submit'])){


foreach($_POST['a'] as $b){

       $c=explode(' ',$b);

	$_SESSION['a']="$c[0]";

	$_SESSION['b']="$c[1]";

	$_SESSION['c']="$c[2]";

	echo $_SESSION['a'];

}

}

?>

[trq]

That makes heaps more sense. Bye.

[redarrow]

here the full code how do you brake the array down to get the sessions to

be indevgally used.............

 

 

when i echo the session out from the posted form the one ecohed session

dispalys all the ordered array from the form

 

<?php session_start();

if(isset($_POST['submit'])){


foreach($_POST['a'] as $b){

       $c=explode(' ',$b);

	$_SESSION['a']="$c[0]";

	$_SESSION['b']="$c[1]";

	$_SESSION['c']="$c[2]";

	echo $_SESSION['a']; //this should be set to this >>$_SESSION['a']="$c[0]"; only but echo them all......

}

}

?>



<form method="POST" action="form.php">

<br>
<input type="text" name="a[]">  
<br>

<br>
<input type="text" name="a[]" > 
<br>


<br>
<input type="text" name="a[]" >
<br>

<br>

<input type="submit" name="submit" value="SEND!">

</form>

why can i not set the session via posting from a form...................

 

simple example.................

 

<?php session_start();

if(isset($_POST['submit'])){

   
    $_SESSION['a']=$_POST['cat'];

	$_SESSION['b']=$_POST['dog'];

	$_SESSION['c']=$_POST['pig'];

	echo $_SESSION['a'];

}


?>



<form method="POST" action="form.php">

<br>
<input type="text" name="pig">  
<br>

<br>
<input type="text" name="dog" > 
<br>


<br>
<input type="text" name="cat" >
<br>

<br>

<input type="submit" name="submit" value="SEND!">

</form>

non array way working need the same way with arrays.......

<?php session_start();

if(isset($_POST['submit'])){

$cat=$_POST['cat'];

$dog=$_POST['dog'];

$pig=$_POST['pig'];
   
    $_SESSION['a']=$cat;

	$_SESSION['b']=$dog;

	$_SESSION['c']=$pig;

	echo"  <br> {$_SESSION['a']} <br> {$_SESSION['b']} <br> {$_SESSION['c']} ";

}


?>



<form method="POST" action="form.php">

<br>
<input type="text" name="pig">  
<br>

<br>
<input type="text" name="dog" > 
<br>


<br>
<input type="text" name="cat" >
<br>

<br>

<input type="submit" name="submit" value="SEND!">

</form>

[redarrow]

<?php session_start();

if(isset($_POST['submit'])){

foreach($_POST['a'] as $b){
   
    $_SESSION['a']=$b[0];

	$_SESSION['b']=$b[1];

	$_SESSION['c']=$b[2];

	echo"  <br> {$_SESSION['a']} <br> {$_SESSION['b']} <br> {$_SESSION['c']} ";

}
}

?>



<form method="POST" action="form.php">

<br>
<input type="text" name="a[]">  
<br>

<br>
<input type="text" name="a[]" >
