Buttons

Kestrell_Kestre

Hello,
Does php have support for buttons or do you have to use the html <button> or <input type=button> format?

My main question is can you run a php function from the onClick action? so I would have

<html type=button name="name" onClick=<?php functionname()?> and then it would go to the php function and do whatever the function has it do?

Is that possible?
Thanks!

That is valid and everything, but it won't do anything I don't think.

The onClick event handler is JavaScript code. I don't quite get what your trying to say but as long as functionname() prints or echos' a JavaScript function or code it will work. You cannot have <?php functionname()?> be the onClick value its' self. The value of onClick (onClick="value") must be JavaScript. PHP is all executed on the server, nothing is done on the client so PHP functions won't work for JavaScript commands. If you are trying to specify a function to call after the form has been sent to the server then try having a hidden field with the function name. Then when action script gets the data it can get the function you want to call from the hidden field. Hope this helps, if not let me know and I'll try to explain it better.

What I want to do is have two input boxes that a user can type numbers into and then a button that will take those numbers and use them in other functions to populate tables further down the page. I had it working where I just pointed to the page again and it "refreshed" with the user inputs, but I don't want to refresh the page because it moves the page back to the top of the viewer.

I have this now:
VD Start (V): <input type=text name="start<?php $deviceType[4]?>" size=3>
VD Stop (V): <input type=text name="stop<?php $deviceType[4]?>" size=3>
<BUTTON onClick="">
<i><font face=arial><b>Correlate!</b></i>
</BUTTON>

and it doesn't work. I had
<form action="CorrelationTemp.php" method="POST">
VD Start (V): <input type=text name="start<?php $deviceType[4]?>" size=3>
VD Stop (V): <input type=text name="stop<?php $deviceType[4]?>" size=3>
<input type=submit name=correlate value="Correlate!!">

which worked but it refreshed and made the browser go back to the top of the page.

I can think of two options at the moment.
First, and probably the easiest: Make an anchor tag where you want the page to be after it's reloaded then set the action script to its self with the anchor tag. Ex:

<form action="CorrelationTemp.php#goHere" method="POST">
....
</form>
....
<a name="goHere"></a>
....

Second, learn JavaScript. 😃

Thats all I can think of at the moment, it's late here. Also, I'm not sure if the first one will work exactly but it's something to try. Hope this helps.
