Hi! I know how to do this in .Net using page.load method but I am clueless when it comes to PHP.

 

The issue I am facing :

 

I have an Array (Session). I enter new values into the Array and it should check for duplicates and then take the element if it is unique. I wrote the code and interestingly, it does a fairly decent job except that it first takes in a duplicate value and from then on it detects the duplicates.

 

I guess it got something to do with the page load like method if any in PHP. Any help is appreciated :)

 

My Code :

 

<?php

 

session_start();

 

$temp = count($_POST['mycheckbox1']);

for($loop2 = 0; $loop2 < $temp; $loop2++){

$_SESSION['softwares'][] = $_POST['mycheckbox1'][$loop2];

}

 

 

if($_POST['txt_software']=='')

echo 'No value selected / Duplicate Software ';

else

{

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

/*foreach ($_SESSION["softwares"] as $tempVal) {

if(strtolower($tempVal)==strtolower(trim($_POST["txt_software"])))

$dupSessionValuesFound=true;

else

$dupSessionValuesFound=false;

}*/

if (!in_array(trim($_POST['txt_software']),$_SESSION["softwares"])){

//if($dupSessionValuesFound=false){

$dupArray=false;

$debug = "submission";

//$duplicateSoftwareFound = false;

 

 

$countSoftware = count($_SESSION['softwares']);

 

for($i=0;$i<$countSoftware;$i++)

{

if(strtolower(trim($_POST["txt_software"]))==strtolower($_SESSION["softwares"][$i]['txt_software']))

$dupArray=true;

}

 

if(!$dupArray)

{

//$_SESSION['softwares'][$countSoftware-1]['text_software'] = $_POST['txt_software'];

$_SESSION['softwares'][] = array();

$countSoftware = count($_SESSION['softwares']);

 

$_SESSION['softwares'][$countSoftware-1]['txt_software'] = trim($_POST['txt_software']);

$_SESSION['softwares'][$countSoftware-1]['text_lab'] = $_POST['txt_lab'];

$_SESSION['softwares'][$countSoftware-1]['text_license'] = $_POST['txt_license'];

$_SESSION['softwares'][$countSoftware-1]['text_media'] = $_POST['txt_install_media'];

}

else

echo "<b><font color=red>Duplicate stuff detected</font></b>";

 

}

else

echo "<b><font color=red>Duplicate stuff detected</font></b>";

}

}

?>

 

<html>

<head>

 

<script type="text/javascript">

 

 

function submit_page (action) {

//alert(action);

switch (action) {

case "done":

document.form1.action = "ConfirmationPage.php";

//alert(document.form1.action);

document.form1.submit();

break;

case "request":

 

 

document.form1.action = "AdditionalSoftware.php";

 

document.form1.submit();
