call to undefine function

Recommended Posts

Hi, when you have a call to undefined function error, that usually means either you misspelled the function name or the function file isn't attached to the page, right?  Can someone help me understand why I'm getting that error?  The function names are spelled the same and the function file is attached so I'm not understanding what 's wrong.

You should be getting a parsing error from the look of it, because your functions are not ended properly.

 

 

function_name() {
   //code
}
In both cases your HEREDOC closing is outside of the end of the function.

 

Furthermore HEREDOCS work like so:

 

$var = <<<HEREDOC
....
HEREDOC;
echo $var;

I think I see what you mean, but I'm still getting a call to undefined function headerInfo()

function headerInfo() {
<<<HEREDOC
<header>
<nav>
	<ul>
    	<li><a href="#">Home</a></li>
    	<li><a href="#">About Us</a>
        	<ul>
       	    	<li><a href="#">Agents</a></li>
		    	<li><a href="#">Locations</a></li>                
			</ul>
      <li><!--end of about us menu list -->   
    	<li><a href="#">Services</a></li>               
    	<li><a href="services.php" tabindex="3" accesskey="S">Services</a></li>
    	<li><a href="quote.php" tabindex="4" accesskey="Q">Get A Quote</a></li>
    	<li><a href="contact.php" tabindex="5" accesskey="C">Contact</a></li>
   </ul>
</nav>  
	<figure id="logo">
   		<img src="assets/bixlerlogo.png" width="304" height="88" alt=""/>
    </figure>
    <h3>Service Beyond The Contract </h3>
</header>
HEREDOC;
}

The PHP tag in the main script around the include statement is malformed:

<php

You need to do it in the php.ini file, not at runtime. The runtime configuration doesn't help you one bit when the error happens before that (e. g. due to syntax problems).

Not to dispute the good advice that Jacques provided, your setting is incorrect. The value s/b "-1" not "1".

The values are correct. display_errors must be 1, error_reporting must be E_ALL.

 

E_ALL can optionally be replaced with -1, but this is an obsolete workaround for early PHP versions where E_ALL didn't actually mean “all errors”. Since PHP 5.4, E_ALL does exactly what it says.

You need echo or return. Such as:

<?php function headerInfo(){ 
return <<<HEREDOC
...
HEREDOC;
} ?>
...
<?php echo headerInfo(); ?>
or

 

<?php function headerInfo(){ 
echo <<<HEREDOC
...
HEREDOC;
} ?>
...
<?php headerInfo(); ?>
Your posts up until now included neither.

 

Note that you don't need to use a HEREDOC at all. You can just exit PHP mode, dump your HTML, then re-enter PHP mode and end the function. I personally find that to be cleaner when dealing with large chunks of HTML, and it sometimes works better with editors tools.

 

<?php function headerInfo(){ ?>
... html here ...
<?php } /* End function headerInfo */ ?>

Actually I prefer the heredocs method for any html over a couple of lines. Makes it easy to output html code and readily accepts php vars with no tags needed!

 

My preferred format (for readability) is the following:

$code=<<<heredocs
...
..
...
heredocs;
echo $code;
No confusion there - everyone knows exactly what is going on.
