PHP Help

[01hanstu]

Hi,

Wondering if someone can help! I need to be able to create a button on my page to clear all the text field on the page.

 

Part of my code is:

     
$i = 1;
while ($i < 7)
{

Then the field name are named mon$i (Where i loops)

 

Just wondering if anyone know where to start with this?

 

Regards

Hi,

Unfortunatly this doesnt work. The fields are generated by php (through the loop).

That's all of it??? That snippet won't even compile.

 

(don't use short-form PHP delimiters, by the way.)

An HTML reset button in your form. This is not a job for PHP.

[localzuk]

This is a job for either a reset button, or Javascript. There's no need for the server side to be doing anything to client-side information.

Hi Guys,

I havce tried this and it does not work. I added a reset button, but on the page it doesn't do a thing!

Can you post a more complete code listing? ie. the code for your page?

[pkkelly]

 
$i = 1; 
while ($i < 7) 
{ 
  $text .= "mon" . $i 
 $i++;
}

 

I'm assuming this is the rest of your code?

 

and you have it in the html like this:

 

 

If I was trying to clear the textarea I would put the text area into a self submitting form and have a php condition to check for a $_POST['reset'] value then reset the value of $text to "" before the form is rendered again... make sense? ;o)

[CESIL]

This javascript will do what I think you want...

 

<br />
function resetAll(){<br />
	for($y=1;$y<4;$y++){<br />
		document.getElementById("mon"+$y).value="";<br />
	}<br />
}<br />




</pre><form action="" method="get" id="aa">









</for

 

If you need to clear a textarea then use .innerText instead of .value on line 4 of the script

[SteveBentley]

if this issue is that $i is dynamic and could be any number, you might have to write the javascript to do the clear with PHP

That would be "guessing".

Self-submit and spend time and resources invoking PHP? WTF? This is the user agent's responsibility, and the correct solution is a reset button.

 

This javascript will do what I think you want...

 

 

Similarly, Javascript is costly overkill. The type is "reset", not "button".

We need more code. Where on the page are you putting the button? There is no reason, even in a php generated html form, for a reset button not to work - emptying fields is what it is designed to do.

[CESIL]

I thought the OP wanted to clear specific fields...the javascript allows that more easily than a reset button which I believe resets all form elements to their default value. I was using a "button" type because I did not want the "reset" button for this use!

 

BTW where do you keep your high horse when you get down off it?

[pkkelly]

WTF?

 

I'm hardly ever in this forum, and don't think I'll come back if this is the kind of attitude that I'm going to get.

You have been presented with a variety of options, all of which should work. Did any of them work? Why doesn't a simple reset button work?

In the paddock next to my stupidity radar.

No personal offence intended. But, really, your solution was very WTF over-engineering.

[pkkelly]

no personal offence intended? lol... what do you expect when you comment someones post with "WTF?" ?!?!

 

anyway... lets not hijack @01hanstu post... btw, did you ever sort this?

Maybe if you didn't take it out of context you'd realise that your solution is stupid, not you.

As he hasn't been back since asking it...

[CESIL]

As he hasn't been back since asking it...

 

...then perhaps one of us helped him...it would be funny if one of our 'stupid' suggestions worked...

[webman]

Sometimes stupid suggestions do actually work, but that doesn't mean they're the right or best way to go about doing something.

...which would make it a solution then?

Buying a tank to drive your kids to school is a solution. A stupid one, but a solution nonetheless.
