Question

Window refresh with php

Asked by: iilv

Hi,

I have a page in which i have iframe whose src is a html file.
The html file has a text field .Its action is a php page which inserts the value into a table.
Currently the html page doesnot show up after i click on submit button but the value get inserted into the table.

If i click on refresh button on the browser the html page inside the iframe appears.

But i want html page to reappear after insertion into a table i.e from php page.

i have tried echo "<script>window.location.reload()</script>" and parent.window.location.reload in php page & also used document.getElementById('iframeid').src='' but still i am not getting the desired result.

Please guide

Thanks

I have done similar things with PHP.  I assume that the form action on the first page is set to a different form that actually does the SQL update.  You could add a line after the SQL update to direct the browser back to the first page like this:
header ("Location: $URL");
...where "$URL" is a variable set to the name of the first page.  If you wanted the first page to show the value that was in the text box when you return to it, you could pass the value as a querystring in "$URL" and then have the first page check for the querystring... and display it in the text box if it's not blank.  That way, the first time you browse to the page normally, the box would be empty.  But if you are directed there from the SQL update page, it would contain a value.
Does that make sense?

There are other options as well.  This is the way I am currently doing it with a few of my own pages.

try this:

<script type="text/javascript">
document.location.reload();
</script>

I have tested it and it works, but let me me know if w need to investigate further

The only problem with the javascript reload is that by the time the insert SQL has been run, a different page will have loaded.  So doing a document.location.reload on the PHP page will only reload that page, not the HTML page that was loaded first.

It looks like you can't manipulate frames with PHP.  See this forum post:http://forums.whirlpool.net.au/forum-replies-archive.cfm/666405.html

It looks like if you want to redirect back, you will need to use JavaScript.  See this post:http://www.pageresource.com/jscript/jredir.htm

Frames are a pain.  I don't use them anymore

There's another option that I've used.  Create a function in JavaScript that changes the form action to be itself, but include a querystring indicator that tells the page that it needs to do the SQL update.  Like this:
document.myForm.action = "myForm.php?update=yes";
Then on that same page at the beginning, check for that querystring.
<?php
  if($_GET[update] == "yes") {
    //do your SQL Insert here
  }
?>
This way, when you first come to the page, 'update' isn't "yes", so the page will skip that SQL insert and load the page.  But when you fill out the text box and click the submit button, the form submits to itself, but this time with 'update' set to "yes"... so it will do the insert and then load the same page.  That should happen in the same frame.
