Html Form Validation

[tobimichigan]

Please could someone help me with a tight code ad that can validate these fields? Please note there r 2 hidden fields, session and date.

 

<form action='Yearly_Entry_Action.php' method='post' enctype='multipart/form-data' name='register'>

Here's the form-action field

 

<?php
include("cn.php");

session_start();

//mt_srand((double)microtime())*1000000;
$session=mt_srand();//create uniqiue sessionid

$date= addslashes($_POST['date']);	
$department = addslashes($_POST['department']);
$essenco=addslashes($_POST['essenco']);
$loanint =addslashes($_POST['loanint']);
$loanrepaid =addslashes($_POST['loanrepaid']);
$month=addslashes($_POST['month']);
$name=addslashes($_POST['name']);
$outloanbal=addslashes($_POST['outloanbal']);
$pfno=addslashes($_POST['pfno']);
$savings=addslashes($_POST['savings']);
$session=addslashes($_POST['session']);
$shares=addslashes($_POST['shares']);
$Year=addslashes($_POST['Year']);		

var_dump($session); die();
$sql= "Insert into yearly_reports(date, department,essenco,loanint,loanrepaid,month,name,outloanbal,pfno,savings,session,shares,Year) values(SYSDATE(),'$department','$essenco','$loanint','$loanrepaid','$month','$name','$outloanbal','$pfno','$savings','$session','$shares','$Year')" or die .mysql_error();  

//$result=mysql_query($sql) or die .mysql_error();		                            
if (!mysql_query($sql))
{
  die('Error: ' . mysql_error()."  SQL: ".$sql);
  }
echo ("1 record added");
?>

 

Very targeted validation would be highly appreciated. Thank you gurus...

If you would like someone to do this for you, i suggest you post it in the freelance board. Otherwise, i suggest you try a little harder. "Here's my code, please finish it for me" is unlikely to cut it.

[mikesta707]

Do you have a specific validation method or do you just want to cleanse the input before you put in the database to protect against SQL injection?

 

here is an example function

Use mysql_real_escape_string() instead of addslashes().

Use the check date function to check if any dates are valid.

Make sure that numbers are actually numbers.

Check if all non-optional fields are filled out.

Mind you, I already have a validation script, but there r 2 hidden fields namely date-registered, and session. Here's my validation script:

 

<?php
if ($_GET["op"]=="reg")
{$blnFlag=false;
foreach ($_POST as $field)
{
if ($field=="")
{$blnputflag=false;
}else
{$blnputflag=true;
}
}
}
if ($blnputflag==false)
{
die("Problem with your registration info."
."Please go back and try again.");
}
?>

 

Hence I want a code-remodification that can validate these forms without tampering with the hidden fields.

Just because a field is hidden, you cannot rely on it. A malicious user could still tamper with the data. You need to validate hidden fields also

That is what I need help for...at least it shows I have done mine homework.
