example requested for basic i/o with php & mysql

[emrys404]

Alright, sorry guys for such a basic question, but i have gone through tutorials, 3 books, and searching the forums etc. but i cant get this basic app to work... arrgh.
Okay, what i want to do is take info form a form on one page and post it on another page. simple stuff. But when i write the damn thing it wont post to the new page...
Could you point me to an example that points this procedure out in detail?

thanks

Okay, let me change my question to something more specific in light of some new information. when using a html form to input data where do you put the php code (opening/saving to database) in relation to the submit button? if you have the form action "mypage.php" does it go to mypage.php before it executes the php code?

Thanks

if you have the form action "mypage.php" does it go to mypage.php before it executes the php code?

When you click the submit button, the data in the form is passed to mypage.php. The script in mypage.php is then executed on the server and the resulting page sent to the browser.

Hey I can actually answer this question 😃 LoL

When using a form , this is the syntax u need:

<form method="post" action="yadda.php">

// Insert your textboxes and stuff here

</form>

Where yadda.php is the file which you want to call, and knowing that yadda.php is in the same directory as the form!

This way, you call up the php-file. The names yu gave to the textboxes, radiobuttons and other form-stuff is then passed to yadda.php in a similar named string. Thus if you have a input that reads :

<input type=text name=adress>

Then the variabele posted for this textbox is called $adress

Hope you understand now 🙂

I have the same problem!!! :mad: I have done what Fraxtc has instructed but i cannot get the variables to transfer from one page to the other. What am i doing wrong? I have read the tuturials and even copied their codes (From http://hotwired.lycos.com/webmonkey/01/48/index2a_page6.html?tw=programming)

But the darn variables cannot transfer! why!???

[barand]

Earlier versions of php (when many of the tutorials were probably written) had a setting in the php.ini files (register_variables) set to ON. This setting is now OFF by default.

This means that variables posted from a form do not get automatically created, you have to get them from the $POST or $GET arrays yourself (depending on your form method (get or post)

$varname = $POST['varname']
or
$varname = $GET['varname']

Alternatively, you could change the setting in the ini file to 'on' or
use

extract($_POST).

However, the last 2 alternatives are not secure.

Thanks, thats the best lead i have had yet. Could you post a more elaborate example on how to use $varname = $_POST['varname'] in a form setting? Thanks alot

Thanks for the generic google reply. But if you had read the previous posts you would find that specific link was already posted on this thread. The first post also mentioned that i had looked through several tutorials and books before posting the question. Next time please read the post in full before posting a generic reply.

Thanks
