querys through url

[joeywoodbury]

I am trying to implement the Prev 123 Next. I am basing it off this article. http://www.phpbuilder.com/columns/rod20000221.php3

I am needing to pass the query through the URL(see last line in article) and I was wondering what is the best way to do so. Is there a way to store the varibles from the form and just pass them into the URL, or do I need to manually add the varibles in the URL, for example: detail.php3?homeid=$row[homeid]&propertyid=$row[propertyid]> to each URL in the script.

Hopefully this is understandable. Please let me know if it isn't.

you can 'store variables in a form' by making them input type=hidden and then they will be passed when the form is submitted (via post or get). OR you can put them manually in the variable, just like you said.

<input type='hidden' name='page' value='2'>

Don't forget to use urlencode() if you plan to append the variables to your URL.

i.e.:
<?php
$myvars = "var1=stuff";
$myvars .= "&var2=things";
?>
<a href="mypage.php?<?php echo urlencode($myvars) ?>">My Link</a>

By using urlencode, you ensure that the variables you are passing will be properly formatted for the URL query string.

Note that if you use a form with hidden fields, you do not need to urlencode the values. However, you should use htmlspecialchars on them so that they do not break the form.

i.e.:
<input type="hidden" name="var1" value="<?php echo htmlspecialchars($var1) ?>">

Hope that helps.

so do I keep adding $myvars .= "&var2=things";
until I have defined all of my vars that I am passing from the form?

And thanks for the help.
