[Resolved] for loop question

phpjaco

hello

im trying to run a rather complex little script that uploads pdfs to a webserver I want to use a for loop to save me some time but cant seem to understand why my code doesnt work and pretty sure its a syntax error.

<?php
  $msg = "hello<br>";
  for ($i=1;$i<6;$i++) {
    if ($heading[$i]) {
	  $msg .= "Headings are : ".$heading[$i]."</br>";
	}
  }
?>

this is just a little script to see if it works but it doesnt, what am i doing wrong here, it suppose to loop six times check if the fields heading1-6 are filled then show a message which displays the heading but nothing happens.

any ideas? thanx in advance.

the loop looks fine.

how is the array $heading defined?

its not really an array, i just called the text input fields heading1 heading2 heading3 etc.

ok... thats ur problem...

something like this may work...


<?php 
  $msg = "hello<br>"; 
  for ($i=1;$i<6;$i++) { 
    if ($heading$i) {
      $msg .= "Headings are : ".$heading$i ."</br>"; 
    } 
  } 
?>

hello

have tried it but this results in a parse error -> have also tried $heading.$i but this gives me numbers?

jonno946

maybe try this...

<?php  

  $msg = "hello<br>";  

  for ($i=1;$i<6;$i++) {  

    if (isset("{$heading{$i}}")) { 
      $msg .= "Headings are : {$heading{$i}}</br>";
    }  

  }  

?>
