Can you make spinner buttons in PHP?

[OldRod]

I've been looking and can't find any examples of using spinner buttons on a form with PHP.

Anyone done this? Does it require javascript? Or can it be done in PHP?

Ok, I found an example using JS, but I can't get it to work.

Here's the code I'm trying (snipped from a larger part obviously):

Code: Select all

<td rowspan=2>Strength: <input type="text" name="str" value=20 size=2></td>
<td><input type="button" value="+" onclick="this.form.str.value++;"></td>
<td><input type="button" value="-" onclick="this.form.str.value--;"></td>

It looks fine on screen, but clicking the button does nothing.

Do I need to do something to activate the code somehow? I've never tried putting Javascript inside of form element before so there's probably something I'm missing.

You can try this:

Give the text field an ID, like this

Code: Select all

<input type="text" value="" id="myBox" />

And to change the value of the box with a button

Code: Select all

<input type="button" value="Hello" onClick="javascript: document.getElementById('myBox').value = 'hello world';" />

Use that and you can probably make your own spin box

Code: Select all

<td><input type="text" id="str" value=20 size=2></td>
<td><input type="button" value="+" onclick="javascript: document.getElementById('str').value++;"></td>

This works - thanks Falken! It's not exactly what you posted, but it pointed me in the right direction
