[Chrysanthus]

Hello to you all!

I need to know how to make a simpel bbcode function.

I have looket all over and i have not mamange to find a simpel exempel here yet on how to do it with a start tag.

the thing is that when i hit B button i want to enter the value <b> and whenne i hit it again the tag will enter a </b> in the end of the last enterd value in the text feald.

<form method="post" action="user-prewin.php" target="preWin" onsubmit="openprewindow()"> 

	<TEXTAREA NAME="pre_view" WRAP="VIRTUAL" style="width: 100%; height: 300px;">

		<?   

			if (!empty($user_pre['presentation'])) {

				echo htmlspecialchars($user_pre['presentation']); 

				} else {

				echo  'Sorry <font color="red">'. $row['username'] .'</font> has not made a presentation yet.</B>';

			}
		?>
	</TEXTAREA>
<br>
Border Size:&nbsp;<input style="width: 20px; height: 16px;" type="text" name="brse_set" size="1" value="<? echo $user_pre['presentationborder'] ?>">
Border Color: #&nbsp;<input style="width: 40px; height: 16px;" type="text" name="brcr_set" size="6" value="<? echo $user_pre['presentationbordercolor'] ?>">
Background Color: #&nbsp;<input  style="width: 40px; height: 16px;"type="text" name="bdcr_set" size="6" value=" <? echo $user_pre['presentationbgcolor'] ?>">
<br><br>

<input type="button" accesskey="b" name="addbbcode1" value=" B " style="font-weight:bold; width: 30px" class="button" onClick="bbstyle(1)"/> 

<br>
<br>
<br>
<br>
<input class="button" type="reset" name="undo_preview" value="Undo">
<input class="button" type="submit" name="preview" value="Preview">

</form>

What you're asking for wouldn't be done in PHP, but in Javascript. Since this forum offers that functionality as an option, the Javascript code for it must be available (probably in an included .js file which, since I don't use the option, I don't have a URL for right now). Probably a matter of an onclick handler that gets the content of the textfield, tacks on the appropriate opening or closing tag (with a bit of string searching to decide which one to use, I guess) and update the textarea's contents. But a Javascript forum would still be a better place for clarification if you need further help.

[Edit: the .js file this forum uses is called vbcode.js]
