Dynamic Creating $_POST

[AllenHobson]

Hi Everyone

I found some code to decrease the writing of $_POST variables especially on big forms, but I cannot seem to get it to work:

 

I am trying to get the $_POST variables from this:

 

<?php
$callsign = $_POST['mf_callsign'];
$surname = $_POST['mf_surname'];
$firstnames = $_POST['mf_firstnames'];
$knownas = $_POST['mf_knownas'];
$rsaid = $_POST['mf_rsaid'];
$birthdate = $_POST['mf_birthdate'];
//more code
[code]

to this (see //Create $_POST Variables section)

[code]
<?php
//Initailise Database first
mysql_connect ("localhost", "***", "***") or die ('I cannot connect to the database because: ' .mysql_error());
mysql_select_db ("***");

=========================
//Create $_POST Variables
foreach($_POST as $inputKey=>$inputValue):

//find all form fields starting with 'mf_'

   if((strstr($inputKey,'mf_') === true)):
      $inputKey = mysql_real_escape_string($inputValue);
   endif;
endforeach;
=========================

//Then do the Insert into the Table
$query="INSERT INTO personal_details (callsign, surname, firstnames, knownas, rsaid, birthdate)Values ('$mf_callsign', '$mf_surname', '$mf_firstnames', '$mf_knownas', '$mf_rsaid', '$mf_birthdate')";

mysql_query($query) or die ('Error Inserting Data into Database');

//If Insert Successful, Goto next Form
header("Location: contactdetails.html");
die;
?>

 

The //Create $_POST Variables section is not correct as it is not setting the variables correctly.

If I go back to the old way and use that ($callsign = $_POST['mf_callsign'] it inserts no problem.

 

What Am I doing wrong?

 

Regards

Off the bat, stop using ===.

 

The triple equals sign means identical in value as well as type.

 

So you're saying if the output of strstr (which is either false, or the part of the string is returned) so in your case would hopefully be a string is identical to true.

 

string mf_ NOT identical to boolean true

 

Try using the equal operator first. ==

try

 

${$inputKey} = mysql_real_escape_string($inputValue);
