Form Refresh with select boxes

[AIX5L]

Hi

My Problem is i have a form with some Adressinformation.
In the Middle of the Form i have a select box with a onchange Javascript Function, which takes the Zip code and put the Cityname in the next Select box. The Problem is when i select the ZIP Select Box all data in my input boxes above.
The Selection is in the Same PHP Script as the Form.
How can i write a Script how keeps my entered Data ?

thanks

If the other fields are a part of the same form as your zipcode field, when that form is submitted, the other fields' data will but available to your PHP script as well as the zipcode.

Your script should conditionally supply the "value" attributes for the other fields.

Assuming you have a field called "name" and that you are using a POST-method form, something like:

print '<input type=&quot;text&quot; name=&quot;name&quot; value=&quot;';

if (isset($_POST['name'])
{
   print $_POST['name'];
}

print '&quot;>&quot;;

This way, if a form value has been submitted, the value will be preserved.

perhaps the solution at thread434-743971 give you an idea.

@sleipnir214 , if you use onchange for reload is the form then submitted also ??

 

[sleipnir214]

If the onchange action submits the form.

That's what I typically do:

<select.....onchange=&quot;this.form.submit();&quot;>

Hi

I have still the same Problem, but i dont know whats wrong:
The Value Firma is selected in the Database:
plz_iz ist also selected in the database:
however the plz, or ort box is changed the value in Name will be cleared:

&lt;input type=&quot;TEXT&quot; NAME=&quot;NAME&quot; value=&lt;? echo $FIRMA; ?&gt;

&lt;select name=&quot;PLZ&quot; onchange=&quot;window.location.replace('&lt;? $PHP_SELF; ?&gt;?plz_id='+window.document.kunde.PLZ.value)&quot;&gt;

&lt;select name=&quot;ORT&quot; onchange=&quot;window.location.replace('&lt;? $PHP_SELF; ?&gt;?plz_id='+window.document.kunde.ORT.value)&quot;&gt;

How i can store the value in the Input Form Name ?

Thanks

Look at the following line:

<input type="TEXT" NAME="NAME" value=<? echo $FIRMA; ?>

One thing you need is to double quote the Firma.

Also, what do you mean by however the plz, or ort box is changed the value in Name will be cleared:
You mean it should be cleared?

Altogether, I would change the approach to what sleipnir214 suggests:
Instead of changing the window.location submit the form. You can do that with client side scripting e.g. JavaScript.

Maybe you can explain your problem in more detail. If need, write in German.

Hi thanks for your reply

I do not exactly understand if your refreshing the page or not. If your not reloading the page and the form is being cleared this might be avoided by using return false clause

<select..... onchange="someJavaScriptFunction();return false;">

At least in my experience multiple event handles sometimes wipes out the form.

Hi

My form is refreshed by the function:
onchange="window.location.replace('<? $PHP_SELF; ?>?plz_id='+window.document.kunde.ORT.value)">

( But why, i don't know )

The return false; doesn't work.

If i need to submit the form, to reload the values, how i can replace the window.location and submit together ?

Some of the posts made yesterday vanished!

What you call 'refresh' is actually submitting the form with GET variables to the script. The page is redrawn.

The vars available in the new page are just the ones you pass as GET parameters - since you have no FIRMA in there it will be gone on the next page.

You can continue using the model you have. What you need to do is attach the other values also as GET parameters:

onchange="window.location.replace('<? $PHP_SELF; ?>?plz_id='+window.document.kunde.ORT.value)+'&firma='window.document.kunde.FIRMA.value">

However, I'd recommend to do it a little different.
