Dropdown Menu Parse Error

TheMouse · Post by **TheMouse** » Tue 15. Feb 2005, 10:39

Hi,

In attempting to implement the CSS Dropdown menu I'm getting a parse error on line five of:

<?php 
// ------------------------------------------------------------- 
if( ! ( strpos($content["all"],'{DROPDOWN')===false ) ) { 
   $content["all"] = str_replace('{DROPDOWN}', '{DROPDOWN:0}', $content["all"]); 
   $replace = 'build_dhtmlmenu('$1','id="nav"',0);'; 
   $content["all"] = preg_replace('/\{DROPDOWN:(\d+)\}/e', $replace, $content["all"]); 
} 
// -------------------------------------------------------------
?>

Locatied in my /public_html/phpwcms_template/inc_script/frontend_init folder.

Can anyone spot the error?

Thanks

1.) this must be placed inside the frontend_render folder:

2.)

Code: Select all

<?php 
// ------------------------------------------------------------- 
if( ! ( strpos($content["all"],'{DROPDOWN')===false ) ) { 
   $content["all"] = str_replace('{DROPDOWN}', '{DROPDOWN:0}', $content["all"]); 
   $replace = 'build_dhtmlmenu( "$1","id=nav", 0);'; 
   $content["all"] = preg_replace('/\{DROPDOWN:(\d+)\}/e', $replace, $content["all"]); 
} 
// ------------------------------------------------------------- 
?>

should do it.

and you have to enable frontend render in conf.inc.php

Thanks for you help but... I just can't get this to work.

I'm no longer getting an error but I'm not getting a dropdown menu either - just a simple <ul> type list where I put the {DROPDOWN} tag.

What am I missing? Can you provide a step-by-step guide?

Thanks

but the list is created correctly from the level that you have specified as startid, right ? then just try the following code:

Code: Select all

<?php 
// ------------------------------------------------------------- 
if( ! ( strpos($content["all"],'{DROPDOWN')===false ) ) { 
   $content["all"] = str_replace('{DROPDOWN}', '{DROPDOWN:0}', $content["all"]); 
   $replace = 'build_dhtmlmenu( $1, id=nav, 0);'; 
   $content["all"] = preg_replace('/\{DROPDOWN:(\d+)\}/e', $replace, $content["all"]); 
} 
// ------------------------------------------------------------- 
?>

in my opinion it would be strange if this was working but just go for it

'

what version do you use...?

brans · Post by **brans** » Tue 15. Feb 2005, 13:50

another solution by pappnase:
$content["all"] = preg_replace('/\{D:(.*?)\}/ie', 'myRT1("$1")', $content["all"]);

so just use:
$content["all"] = preg_replace('/\{DROPDOWN:(.*?)\}/ie', 'build_dhtmlmenu("$1")', $content["all"]);

but then you will always have to specify the following:
{DROPDOWN:0,id="nav",0}
change the parameters as needed.

Ohhh yes! Is that right: You have created a dhtmlmenu but you haven't actually added any css but the list is created correctly with the id parameter added ?

<ul id="nav"><li>.....</ul> ?!?

In ordner to get the css menu running, you will have to implement some JS or css or whatever... just search try to search for:

keyword: css

keyword: css

Thanks to you all.

After all that I'm not sure what was causing the problem! I started again using your advice and this time it works.

The problem was definitely related to the creation of the dhtml list though - it was not being created with the 'nav' id.

Thanks again

Mouse.

btw I think there is definitely a need for a 'beginners guide to dropdown menus'

brans · Post by **brans** » Tue 15. Feb 2005, 14:33

ok please tell me what code was finally working for you so that I can create some tutorial at our dev site... And what version of phpwcms are you using ?

TheMouse · Post by **TheMouse** » Tue 15. Feb 2005, 15:24

THe code I'm using now is:

In the render directory:

Code: Select all

<?php
if( ! ( strpos($content["all"],'{DROPDOWN')===false ) ) { 
   $content["all"] = str_replace('{DROPDOWN}', '{DROPDOWN:0}', $content["all"]); 
   $replace = 'build_dhtmlmenu( "$1","id=nav", 0);'; 
   $content["all"] = preg_replace('/\{DROPDOWN:(\d+)\}/e', $replace, $content["all"]); 
} 
?>

in the dropdown.js in the inc_js directory:

Code: Select all

sfHover = function() {
	var sfEls = document.getElementById("nav").getElementsByTagName("LI");
	for (var i=0; i<sfEls.length; i++) {
		sfEls[i].onmouseover=function() {
			this.className+=" sfhover";
		}
		sfEls[i].onmouseout=function() {
			this.className=this.className.replace(new RegExp(" sfhover\\b"), "");
		}
	}
}
if (window.attachEvent) window.attachEvent("onload", sfHover);

and in the frontend.css file:

Code: Select all

/* BEGIN Menu Definitions */

#nav, #nav ul {
	position: absolute;
	top: 130px;
	*/float: left;*/
	width: auto;

	background-image:url(/img/nav_btm_hover.gif);
	background-repeat: repeat-x;

}

/* END Menu Definitions */

Most of this is from this thread: http://www.phpwcms.de/forum/viewtopic.php?t=5361
It still isn't behaving quite right though - see http://www.aurabeauty.co.uk/index.php

hi,
i tried to setup the dropdown menu and get this error:

Code: Select all

Fatal error: Call to undefined function: build_dhtmlmenu() in /www/htdocs/xxx/phpwcms_template/inc_script/frontend_render/reptag_dropdown.php(6) : regexp code on line 1

On Line 1 is only the opening php tag...

What does it mean?

I have put the files in the folders, set frontend_init and frontend_render to 1 in config.php?

Thanks for tips.

Can the vertikal and horizontal menu function used both at the same time?

TheMouse · Post by **TheMouse** » Sun 20. Feb 2005, 10:58

Sounds like you need this code:

Code: Select all

function build_dhtmlmenu($start=0, $class, $counter=0) { 
   $s = ''; 
   $g = ''; 
   foreach($GLOBALS['content']['struct'] as $key => $value) { 
      if ($start == $GLOBALS['content']['struct'][$key]['acat_struct'] && 
         !$GLOBALS['content']['struct'][$key]['acat_hidden'] && $key) 
      { 
         $s .= '<li>'; 
         if(!$GLOBALS['content']['struct'][$key]["acat_redirect"]) { 
         $s .= '<a href="index.php?'; 
            if($GLOBALS['content']['struct'][$key]['acat_alias']) { 
               $s .= $GLOBALS['content']['struct'][$key]['acat_alias']; 
            } else { 
               $s .= 'id='.$key.',0,0,1,0,0'; 
            } 
            $s .= '">'; 
         } else { 
            $redirect = get_redirect_link($GLOBALS['content']['struct'][$key]["acat_redirect"], ' ', ''); 
            $s .= '<a href="'.$redirect['link'].'"'.$redirect['target'].'>'; 
         } 
         $s .= html_specialchars($GLOBALS['content']['struct'][$key]['acat_name']); 
         $s .= '</a>'; 
         $s .= build_dhtmlmenu($key, $class, $counter+1); 
         $s .= "</li>\n"; 
      } 
   } 
   if($s) { 
      $g  = "\n<ul"; 
      if(!$counter && $class) $g .= ' '.$class; 
      $g .= ">\n".$s.'</ul>'; 
   } 
   return $g; 
}

in a .php file in your /phpwcms_template/inc_script/frontend_render/ directory.

I think this function is included in the latest build of phpwcms but it wasn't in mine.

HTH

yes this code is only included from DEV 1.1.5 on, I will add this notice to the dev site.

Hi Mouse, hi brans,

thanx for your hints.

I added the code Mouse has shown into a php-file and put in the frontend_render folder in a 1.1 RC 27-08-04 version, but still lacks...

I got the same error.

Is it right that it works only in the dev releases since 1.2?

There it works, but not with older ones...

Frontend Rendering is a new Function - it is not avaible in 1.1 RC4
