when submit add variable to url

oaskedal

Hi!

How can I make this happen? I've tried to find an answer in the forum, but I didn't. I'm only a newbie in codin' ,so please bare with me..

Ok, I'd like a script to attach the following to the my URL variable:

if it's the first time I've clicked my 'Attach' button, attach this:

?table=$name

to the variable URL.

If it is the second time or more, add the following to the variable URL (assuming ..domain.no?table=$name already there):

&table=$name;"

The variable should in other terms update everytime I hit my 'attach' button.

Could this be done with an array, and some loop? I'm not sure how to start...

Try something like this:

$myURL = 'http://www.mydomain/index.php';

if (ereg("?",$myURL)) {
   $myURL = $myURL.'&table='.$name;
} else {
   $myURL = $myURL.'?table='.$name;
}

Why do you want to do that? The second table=$name will override the first.

Try something like this:

Please do not recommend the ereg family of regular expression functions. Recommend the PCRE functions instead. In this case, regex is overkill as [man]strpos/man will suffice. Depending on what oaskedal really wants to do, it may be even better to use [man]parse_url/man, [man]parse_str/man and [man]http_build_query/man.

Ok, maybe some more details will do 🙂

When I push the 'attach' button the first time, the following should be added to the $url (which before this operation only contain e.g. 'page2.php'):

?table=$name

the second time I push the 'attach' button, the following should be added to the $url (which before this operation should contain 'page2.php?table=$name'):

&table2=$name

the third time I push the 'attach' button, the following should be added to the $url (which before this operation should contain 'somepage.php?table=$name&table2=$name'):

&table3= $name

and so on...

So, why this script?
I will use it to verify my different session arrays on the next page (the place where the page2.php should go to in the end). A new session array is stored every time I hit the 'attach' button, and the name of it is $name. That way I can identify them, when I hit my 'finished' button and are sent to page2.php... Here I will print them all to the screen, so the user can see what input he did on the previous page..

If there's another way around - please let me know :-)

I hope this was not to complicated...:queasy:

Ah, that makes more sense. What zzz suggested should be fine, though change ereg() to use [man]strpos/man.

Ok, thanks! I'll try it, but what if I'd like to extend 'Tabell' in the URL each time with a number, say:

?Tabell=$name

&Tabell_2=$name

&Tabell_3=$name

and so on..

Also, wouldn't the second table=$name override the first as you mentioned?

Any thoughts? 😕

You would need a counter that can also be appended to the query string.

With a number appended to the name, the name is different.

Actually, come to think of it:

Why not just use a session array of arrays?

Hi!

Thanks for your answer. Yes your last solution sounds bulletproof.
However I need to give the session variable a new name each time or the values already stored will be overwritten. How would you implement that counter?

I would use numerically indexed arrays instead of associative arrays, since you originally wanted to use names like table1, table2, tableN anyway.

I tried this as another way around, but it gave me the same result..only overwriting my first input everytime I hit the 'myButton'... Strange..

  

      if($_POST['myButton']) { //when button is hit



          $name = $_POST['tablename']; //fetched from form in same page

          $fieldname = $_POST['fieldname']; //fetched from form in same page

          $fieldvalue = $_POST['fieldvalue']; // fetched from form in same page





          $_SESSION['mySession'][] = array("Tablename"=>$name, "Subject"=>$fieldname,"Value"=>$fieldvalue);



          echo "<table><tr><td><pre>";



          print_r($_SESSION['mySession']);


          echo "</pre></td></tr></table>";



}

          echo "</pre></td></tr></table>";



}

OOps! I found my problem. Turns out I had put a unset($_SESSION['mySession']) on the start of the page... Now it is all OK!
