Can PHP automatically submit forms like Javascript.

@zincoxideJan 01.2005

I have a page with a list of products (products.htm). When the user clicks the buy now button it opens another page (page2.php).

In page two I have imported through hidden variables all the variables on products.htm (using $_POST). A script will then determine which company was selected…

If Company A was selected I want to submit a form to open a new page called CompA.php (importing all the same hidden variables)

If Company B was selected I want to submit a form to open a new page called CompB.php (importing all the same hidden variables)

And so on…

I have got it working except for submitting a new form (CompA.php/CompB.php). I tried something like this:

[code] echo “<form method=’post’ action=’/CompA.php’>”; echo “<input type=’hidden’ value=’$_POST[“CompanyName”]’>”; echo “<input type=’hidden’ value=’$_POST[“Product”]’>”; echo “document.this.form.submit()”; echo “</form>”; [/code]

it doesn’t submit the form but… if I make an active submit button then it does work…

What I want to know is how to force a submit like in javascript..

Can anyone help me???

@ShrineDesignsJan 01.2005 — #why not do a redirect on page2.php, instead of re-submiting the data, for example:

[code=php]<?php
 if($_POST)
 {
 if(!empty($_POST['CompanyName']))
 {
 switch($_POST['CompanyName'])
 {
 case 'CompA':
 $url = 'CompA.htm';
 break;
 // and so on ...
 }
 header("Location: {$_SERVER['HTTP_HOST']}/{$url}");
 exit;
 }
 else
 {
 exit("you did not select a Company");
 }
 }
 else
 {
 exit("no data was submitted");
 }
 ?>[/code]

@zincoxideauthorJan 01.2005 — #I think that will work...

I am not familiar with php tho... I don't need to have a safety as far as "no company selected". The only way they would get to this page is if they click the buy now button which, the way everything is set up always has data in it.

What I want to set up is:

If company a goto this page

if company b goto this page

if company c goto this page

if company d goto this page

if any other company goto a generica page

The only reason why I had "Worked and Didn't Work" is because I was trying to figure out how to do it.

If I did this would it work???

<i>
 </i>&lt;?php
 if($_POST)
 {
 switch($_POST)
 {
 case 'CompA':
 $url = 'CompA.htm';
 break;
 // and so on ...
 }
 header("Location: {$_SERVER['HTTP_HOST']}/{$url}");
 exit;
 }
 else
 {
 switch($_POST)
 { $url = 'Generic.htm'; }
 }
 ?&gt;

I don't know something like that???

Also what does this do:

<i>
 </i>        header("Location: {$_SERVER['HTTP_HOST']}/{$url}");
 exit;

@zincoxideauthorJan 01.2005 — #On second thought, will that "drag the $_POST array into CompA.htm"???

This is what I need to do.

@ShrineDesignsJan 01.2005 — #you will need to change and/or add to this in order for it to work:

 case 'CompA':
 $url = 'CompA.htm';
 break;

this is a server-side redirect:

 header("Location: {$_SERVER['HTTP_HOST']}/{$url}");
 exit;

[/B][/QUOTE]
I was of the understanding that a "complete" URL was required for the [b]Location[/b] header:

<i>
 </i>header("Location: http&amp;#58;//{$_SERVER['HTTP_HOST']}/{$url}");
 exit;

@ShrineDesignsJan 01.2005 — #a mistake on my part

header("Location: http://www.{$_SERVER['HTTP_HOST']}/{$url}");
 exit;

header("Location: /{$url}");
 exit;

for HTTP 1.1 an absolute uri is required, and for HTTP 1.0 a relative uri is allowed

@zincoxideauthorJan 01.2005 — #Okay... But... Will it drag in the $_POST array into the destination page. This is absolutely crucial for me.

@phpnoviceJan 01.2005 — #No, sorry, it will not. Generally, you would have to reformat the POST data into a query string (GET-type data) and attach it to the redirected URL.

<i>

 echo "&lt;input type='hidden' value='$_POST["CompanyName"]'&gt;";
 echo "&lt;input type='hidden' value='$_POST["Product"]'&gt;";
 echo "document.this.form.submit()";
 echo "&lt;/form&gt;";

To force a submit, you would modify the BODY tag as follows -- e.g.:

<i>
 </i>&lt;body onload="document.forms[0].submit();"&gt;

Keep in mind that the client must have JavaScript enabled, though.
