[RESOLVED] onclick?

kansaschuck

Hi,

I'm trying to add some conditional process in my html / php page. I'd like to give viewers of the page the option (button) to click that would then execute a .php script.

It should be fairly easy. But my command does nothing. Even when I put in a bogus script name. No errors or anything.

Can someone take a look and give me some guidance?

echo '<FORM>';
echo '<TABLE BORDER CELLPADDING=3>';
echo '<TR>';
echo '<TD><INPUT TYPE=BUTTON OnClick="/mysite/yada/public_html/neutral_area/text_grab.php;" VALUE="Reload"></TD>';

echo ' </TR>';
echo '</TABLE>';
echo '</FORM>';

The onclick attribute is only going to issue a JavaScript command (remember that it is running on the client side, not on the server side where your PHP scripts are). Depending on what exactly you want to have happen when that button is clicked, you'll need to use some corresponding JavaScript function: either a window.location() command, one of the AJAX-related commands, etc.

Thanks for the reply. The click needs to activate a .php script on the server. I would make modification in a .txt file and then a refresh of the html page would display the text. No need for java the script action is all server code.

I hope that helps.

Is there any reason not to use a HTML <form> then to submit the request?

<form action="/mysite/yada/public_html/neutral_area/text_grab.php" name="reload" method="post">
<input type="submit" name="submit" value="Reload" />
</form>

when that is clicked, it will goto that page and perform w/e script is there... u can modify your script there todo a header("Location: url"); to send the user back to the other page after the processing is done

if u want it to be seamless youll have to use AJAX

Ok... here's the current code.

echo '<form name="input"'; 
echo ' action="http://mysite/scgi-bin/text_grab.php"';

// echo 'method="get">';
echo 'Refresh:  type REFRESH and submit  '; 
// echo '<input type="text" name="type REFRESH and submit">';
echo '<input type="submit" value="Submit">';
echo '</form>';

echo '<FORM>';
echo '<INPUT TYPE="button" onClick="history.go(0)" VALUE="Refresh Page ">';
echo '</FORM>';

So it's working but not very elegant. Rather than have a script run every couple of minutes I'm letting the viewer initate the script. No info is passed to the script it just runs and thus the commented out code that feed info to the script.

They come to the site and after reading some doc they need to initiate the .php script. That will cause a file to be updated and then the page needs refreshed (htlm/php reads the file that was just updated by the user activated php script.)

I think those actions could be all one if there was a brief delay. Next up I need to consider that affect multiple user would have on the site/scripts.

any advice welcome.

you need to close that first open form element:

echo '<form name="input"';
echo ' action="http://mysite/scgi-bin/text_grab.php">';

Can't you just do the following instead of multiple echo commands?

echo "<form name='input' action='http://mysite/scgi-bin/text_grab.php'>";

scrupul0us

yes

some people use multiple echo's to help maintain the visual hierarchy

Thanks all.
