How do you receive the data when you click the submit button of a form?

After I add a button and a text field, how can I program that button to simply take what's in the text box and put it into a variable? I have no idea how the button click event works.

<form id="form1" name="form1" method="post" action="">
  <label>
    <input type="submit" name="Searchbydistro" id="Searchbydistro" value="Submit" onclick="xxxxxxxxx " />
  </label>
  <label>
    <input type="text" name="txtboxsearchbydistro" id="txtboxsearchbydistro" />
  </label>
</form>

Would I put a PHP statement in the space where the xxxxxxxx is at?

Any help would be great!

You can't execute PHP code in onclick() statements because PHP gets executed on the server, before the page is sent to the browser, and the onclick() function is exectued at the browser.

Solution would be (assuming this page is form.php) set the action of the form for "form.php" and on that page have

if(isset($_POST)){
   $variable = $_POST['txtboxsearchbydistro'];
   // Here you can run validation on $variable, sanitize it and pass it to a DB query
}

No, php is server-side, and onClick is client-side event.

I'm not entirely sure what are you trying to accomplish. If you wish to submit your txtboxsearchbydistro value to some PHP script, you would put something like this:

<form id="form1" name="form1" method="post" action="somePhpScript.php">

Then you would use something like Bobby proposed.

If you wish to do something before you actually send the form, or you want to do something on client side (i.e. in visitor's browser), you'd need to do something like

<input type="submit" name="Searchbydistro" id="Searchbydistro" value="Submit" onclick="myScript();" />

You could then need to define your script, and assign your value there.

Hope it helps.
