PHP - Logical Way Of Doing This

Hi guys, i'm trying to increment a variable / session value whenever 'submit' comes in the POST.

I can't seem to get around the logic of this.

Code looks like this:

Code: [Select]
$var = 0
if($_POST('submit'){
$_SESSION['var2'] = $var++;
}

What I want it to do is increment the value of the session index everytime a user clicks 'submit'.

But because i've reset $var to 0 everytime, it's always just going to stay at 1.

I just can't think of a way to achieve this, does anyone have any clue on how I can?

fixed.

Hi there,

First of all, I want to present the diagram that I'm working on.
-----------
Diagram
-----------
step2_a.php --|
step2_b.php --|---> output.php
step2_c.php --|       (Process is included here)
step2_d.php --|


and here are the corresponding codes:

step2_x:
Code: [Select]
. . .
<form action="output.php" method="post" name="a">
req1: <input type="text" name="a_req_1">
req2: <input type="text" name="a_req_2">
. . .
<input type="submit">
</form>
------
. . .
<form action="output.php" method="post" name="b">
req1: <input type="text" name="b_req_1">
req2: <input type="text" name="b_req_2">
. . .
<input type="submit">
</form>
. . .
. . .

output.php:
Code: [Select]
<?php
$form_name = $_POST['a'];
if($form_name = "a") {
//variables for a goes here
        //code goes here
}
elseif($form_name = "b") {
//variables for b goes here
        //code goes here
}
elseif($form_name = "c") {
//cariables for c goes here
        //code goes here
}
elseif($form_name = "d") {
//variables for d goes here
        //code goes here
}
else {
//code goes here
}
?>
Now, here's the problem. output.php always sees the primary condition as true. Even the data came from step2_b, the code does not recognize it. I tried to use "==" instead of "=" but the code sees the arguments as false so it executed the code on "else".

How can I make the code distinguish the source of the data so that it would execute the right set of commands?

Thanks in advance.

I am creating a form that collects the details of users and then any errors cause for the error log to have errors noted and added to it.

Part of my coding is this:

Code: [Select]
else if (is_numeric($name)||is_int($name) && is_numeric($surname)||is_int($surname))
{
echo "It seems that you have entered numerical values for the First Name and Surname fields. This has been added to the error log.<br><br>";
error_log("<br><br><b><u>Presence Error</b></u><br>The user has entered numerical values for First Name and Surname fields!<br>First Name entered: " . $name . "<br>Surname entered: " . $surname . "<br>Age entered: " . $age . "<br>Number Of Complete Weeks Since Accident entered: " . $weeks . "<br>Time that form was submitted: " . $subtime . "<br><br>", 3, "C:/xampp/htdocs/errorlog.txt");
}
else if (is_numeric($name)||is_int($name))
{
echo "It seems that you have entered a numerical value for the First Name field. This has been added to the error log.<br><br>";
error_log("<br><br><b><u>Presence Error</b></u><br>The user has entered a numerical value for First Name fields!<br>First Name entered: " . $name . "<br>Surname entered: " . $surname . "<br>Age entered: " . $age . "<br>Number Of Complete Weeks Since Accident entered: " . $weeks . "<br>Time that form was submitted: " . $subtime . "<br><br>", 3, "C:/xampp/htdocs/errorlog.txt");
}
else if (is_numeric($surname)||is_int($surname))
{
echo "It seems that you have entered a numerical value for the Surname field. This has been added to the error log.<br><br>";
error_log("<br><br><b><u>Presence Error</b></u><br>The user has entered a numerical value for the Surname field!<br>First Name entered: " . $name . "<br>Surname entered: " . $surname . "<br>Age entered: " . $age . "<br>Number Of Complete Weeks Since Accident entered: " . $weeks . "<br>Time that form was submitted: " . $subtime . "<br><br>", 3, "C:/xampp/htdocs/errorlog.txt");
}

so that if a user enters in numerical values when letters need to be entered, then this gets added to the error log. However, even if I enter in a suitable surname (i.e. Jones), the first path (where both the first name and surname are detected as being numerical) runs when I want the path where only the first name contains just digits to be run. Any idea how to fix this?

Any help is appreciated!

Thanks!
