When the submit button with the name "button" is pressed it will post this information to the target page. Likewise, when the submit button with the name "button2" is pressed that information will be passed to the target page as well. All you have to do is test to see which button name is part of the posted variables and then treat the submission accordingly.
Try something like this:
Code:
<?php
if (isset($_POST['button2'])) {
//process your data first
$db = mysql_connect("localhost");
mysql_select_db("job", $db);
$addcv = mysql_query("insert into cv
(
degree,
cgpa,
institute
)
values
(
'".$degree."',
'".$cgpa."',
'".$institute."',
)");
//then send user to the url for the next step
header( 'Location: http://www.yoursite.com/new_page.html' ) ;
}
else if (isset($_POST['button'])) {
//process your data and do nothing else
$db = mysql_connect("localhost");
mysql_select_db("job", $db);
$addcv = mysql_query("insert into cv
(
degree,
cgpa,
institute
)
values
(
'".$degree."',
'".$cgpa."',
'".$institute."',
)");
echo "Your data is added.";
}
?>

be sure to replace the field part with the form field names and what this does is starts a session and creates 3 session variables and gives them the values from the form to be recalled on anypage u chose after this and all u have to do to access these variables is include the session_start() at the top of any page u wish to use them variables on but i would recommend putting it on every page
I studied up on sessions a bit and took a stab at it since I'm finding it to be a hole in my own skills.
Here is a basic sandbox file that you can take apart and get to know:
Code:
<?php
session_start();
if(isset($_SESSION)) {
if (isset($_POST['logout'])) {
//to reset page session...
unset($_SESSION['degrees']);
unset($_SESSION['cgpas']);
unset($_SESSION['institutes']);
unset($_SESSION['favorite_foods']);
unset($_SESSION['hair_colors']);
unset($_SESSION['heights']);
session_destroy();
}
else {
if(isset($_SESSION['degrees'])) {
if (isset($_POST['save_and_add']) || isset($_POST['save_and_continue'])) {
if (isset($_POST['degree_name'])) {
array_push($_SESSION['degrees'],$_POST['degree_name']);
}
}
}
else {
$_SESSION['degrees']=array();
}
if(isset($_SESSION['cgpas'])) {
if (isset($_POST['save_and_add']) || isset($_POST['save_and_continue'])) {
if (isset($_POST['cgpa'])) {
array_push($_SESSION['cgpas'],$_POST['cgpa']);
}
}
}
else {
$_SESSION['cgpas']=array();
}
if(isset($_SESSION['institutes'])) {
if (isset($_POST['save_and_add']) || isset($_POST['save_and_continue'])) {
if (isset($_POST['institute'])) {
array_push($_SESSION['institutes'],$_POST['institute']);
}
}
}
else {
$_SESSION['institutes']=array();
}
if(isset($_SESSION['favorite_foods'])) {
if (isset($_POST['save_and_add']) || isset($_POST['save_and_continue'])) {
if (isset($_POST['favorite_food'])) {
array_push($_SESSION['favorite_foods'],$_POST['favorite_food']);
}
}
}
else {
$_SESSION['favorite_foods']=array();
}
if(isset($_SESSION['hair_colors'])) {
if (isset($_POST['save_and_add']) || isset($_POST['save_and_continue'])) {
if (isset($_POST['hair_color'])) {
array_push($_SESSION['hair_colors'],$_POST['hair_color']);
}
}
}
else {
$_SESSION['hair_colors']=array();
}
if(isset($_SESSION['heights'])) {
if (isset($_POST['save_and_add']) || isset($_POST['save_and_continue'])) {
if (isset($_POST['height'])) {
array_push($_SESSION['heights'],$_POST['height']);
}
}
}
else {
$_SESSION['heights']=array();
}
}
}

I have no idea if this code is efficient or secure in any way (it probably isn't efficient and it definitely needs data sanitation built in to prevent hacking attempts), but it does save the variables across the form steps just fine. The DB portions have been commented out since I didn't bother to hook up a DB to this. When you take this live you would want to adjust WHEN the information is saved or else you will potentially get a lot of redundant entries. I haven't tested or debugged for that part of the script AT ALL, only the session variables and form stages have been tested.
Also, when you go live you would want to insert error handling both via javascript and also with PHP to make sure that only valid data sets are entered into the session variables (for example, you don't want to insert blank values if the user should instead be prompted to fill out the form in its entirety).
Let me know if you have any questions about this test script...
be sure to replace the field part with the form field names and what this does is starts a session and creates 3 session variables and gives them the values from the form to be recalled on anypage u chose after this and all u have to do to access these variables is include the session_start() at the top of any page u wish to use them variables on but i would recommend putting it on every page
i apply sessions but says an error. what i did is here
this is my first page
Notice: Undefined index: degree in D:\wamp\www\examples\next.php on line 12
Notice: Undefined index: cgpa in D:\wamp\www\examples\next.php on line 13
Notice: Undefined index: institute in D:\wamp\www\examples\next.php on line 14
what could be the reason? why are they not getting pass to another page?
help
bcuz ur no longer posting data from one page to the next and u must declare that the session is being used on this page so u must add that b4 u try and call up any session variables
You will continually overwrite your session data with only the most recent value. Session variables work like arrays (in fact they are arrays) and you should be pushing that value onto the correct array rather than assigning it.
The code I provided works completely for session data storage so I'm not sure why you haven't worked with that example code. You might at least give it a try.
Anyway, even if you are going this route instead it is very important that you remember to sanitize your data and provide error checking for your forms.
No matter what method you use for your data collection if you don't sanitize your data before passing it along to the session (or worse, your database) you leave yourself open to bad data (if you're lucky) and/or many successful hacking attempts (if you aren't so lucky). For one easy example just google SQL injection...
As I said before, solutions for this should be implemented in BOTH javascript and your PHP code. Javascript is there to catch errors before they make it to the server (saving bandwidth and server load - especially for common and non-hostile data errors) and PHP is there as insurance to catch those same errors if and when they actually do reach the server. The PHP end is of paramount importance when thwarting hacking attempts since this is where you can stop a hacker from inputting a string of code to damage or infiltrate your system rather than true data.
