Post through dropdown menu

Ros

Hello,

I have a dropdown menu. Now I wish to post the value I have selected right after the selection without pushing any submit button.

How do I do that?

Many Thanks

With an onChange event . HTML Events


<input type="select" onChange="submit()">

Hey Roger,

Thanks a lot for the tip. It works fine.

i just dont understand something.

Through the

<?php

echo "
<Form name='Form1' action=\"test.php\" methode=\"post\">
<Select name='isList' onchange=\"submit(this.value)\" </Select>
</Form>";

if (isset($_POST['submit'])) {
    echo($_POST['isList']);
}
?>

The code above is in the test.php. So I am posting the value through the selection to the same page.

I was hoping to catch the $_POST and just echo the value I had selected before. It doesn't echo the selection which means the POST is not working properly. Do you have any idea what could be wrong in the code?

Thanks a lot,
Ros

Well I just use onChange="submit()" myself. At the very least the (this.value) is redundant as the form will submit and the select is set so it will post the selected value.

Your main problem though is that you are testing for a post var named 'submit', but your form does not have an input element named submit now does it. You should be testing for isset($_POST['isList']).

In future, to debug your post vars use


foreach ($_POST as $key=>$val) {
   echo $key . ' = ' . $val . '<br />';
}

to see which vars exist and what they contain

Hi Roger,

I tried it out without success. I even have send the POST to a different page called 'test2.php. I have placed your debugger loop into that, still without any success.

Could you please check out the example.

(By the way the Javascript code is not clean yet, FirFox won;t work. Use IE)

What could be wrong? I mean at least something should be in the POST value as it is visible in the address bar. 😕

Now I'll bet you can tell me what is wrong with this

  methode="post">

Can't you?

And another Dooh! moment occurs :o

Ros

You like your javascript don't you. Look, is it absolutely neccessary to do it that way? You will end up with a website that only works with IE. Now it may seem OK, but like you say "FirFox won;t work. Use IE". Well, I banned IE here last year, just too many malicious websites around f***ing up my network. You will find that more and more users are turning to more secure browsers like Firefox, NS 7, Opera. Making any website that only functions in IE is a sure way to loose business and users.

No no there is misunderstanding. I am totally aware of FireFox. I am using FireFox right now. The javascript code isn't clean and it is not even mine.

Someone from another Forum tried to help me to make an autocomplete dropdownmenu thing.

Well, so far I have found other examples or lets say better code which works fine with FireFox.

I will replace that later. This was just a prototype to see how PHP works.

OK, I was not having a go at you, just reminding you to be carefull. Just that since changing our company browser I keep coming across websites that only work with IE6. One of our girl's can't do her grocery shopping online anymore as ASDA only works with IE6. I'm sure the pratts who developed ASDA's website are so proud of how clever they are - I just call them amateurs.

Ros

It is true what you say. Its never good if your site is just working with one special browser.

Besides FireFox got so popular, even much more than Opera, which is just crazy to ignore so many users.
