[Resolved] using php with a javascript messagebox...

[netooio]

Hi.. here's what i'm doing..

<input type=button value="Show Answer" name="btnShowAnswer" onClick="MsgBox(<?php $currentanswer ?>)"></p>

MsgBox is a javascript function i made earlier in the webpage..

I'd like to be able to somehow use php to insert a string to display in the message box but the above doesnt work..
Does anyone have any suggestions on how to get this to work.?

u have to do "echo $currentanswer;" php generates html pages so right now ur doing nothing but stating a variable.. ur not generating the text for it 😉

I've tried using that before...

<input type=button value="Show Answer" name="btnShowAnswer" onClick="MsgBox(<?php echo $currentanswer ?>)"></p>

but when i click on the show answer button it gives me an error messagebox popup saying a runtime error has occured..
'Heart' is undefined...

(heart is the answer btw)..

when i do echo $currentanswer, that tries to echo it to the screen correct? I'm just looking to somehow insert that value of $currentanswer as the message string for the MsgBox function.

ur missing the ;
and where does heart come from? what is $currentanswer have u defined it before? More code would help us find the answer

<SCRIPT LANGUAGE="JavaScript">

function MsgBox (textstring) {alert (textstring) }

</SCRIPT>

$currentanswer contains the string "Heart"...

I've echoed it out to the screen before and know that it contains it.

<input type=button value="Show Answer" name="btnShowAnswer" onClick="MsgBox(<?php echo $currentanswer; ?>)"></p>

I have tried adding the semicolon before.. that was just a typo..
It resulted in the same error as described above...

Thats all the code relating to this problem...
I am creating a webpage that asks study questions and i have a button that says show answer that I want to pop up the correct answer to the current question.

I just need the string that is in the php variable $currentanswer to be my message string in the MsgBox function and I cant quite figure out how to do that if its possible to do.

<input type=button value="Show Answer" name="btnShowAnswer" onClick="MsgBox('<?php $currentanswer ?>' )"></p>

use ' ' before and after the PHP tags
