Adding custom module position cause double rendered modules on site

Posted 10 years 8 months ago

Reproduction:
* Gantry Rocketlauncher v4.2.21 (After install update to latest joomla, purge chaches)

### Edit template
add html in index.php

Setup a custom module to fullwidthmenu-a position with simple <h1> tag content

Result:

After inspecting the code in the browser, i'll noticed that the module is rendered too in fullwidth

### Scenario 2
The same results you'll get if you add 2 modulepositions with similar names, like (headertop and headerbottom):

        <fields name="headertop" type="position" label="HEADERTOP_POS" description="LAYOUT_POS_DESC">
            <field name="layout" type="positions" default="3,3,3,3" label="">
                <schemas>1,2,3,4,5,6</schemas>
                <words>2,3,4,5,6,7,8,9,10</words>
            </field>
            <field name="showall" type="toggle" default="0" label="FORCE_POS"/>
            <field name="showmax" type="showmax" default="6" label="POS_COUNT"/>
        </fields>


        <fields name="header" type="position" label="HEADER_POS" description="LAYOUT_POS_DESC">
            <field name="layout" type="positions" default="3,3,3,3" label="">
                <schemas>1,2,3,4,5,6</schemas>
                <words>2,3,4,5,6,7,8,9,10</words>
            </field>
            <field name="showall" type="toggle" default="0" label="FORCE_POS"/>
            <field name="showmax" type="showmax" default="6" label="POS_COUNT"/>
        </fields>

        <fields name="headerbottom" type="position" label="HEADERBOTTOM_POS" description="LAYOUT_POS_DESC">
            <field name="layout" type="positions" default="3,3,3,3" label="">
                <schemas>1,2,3,4,5,6</schemas>
                <words>2,3,4,5,6,7,8,9,10</words>
            </field>
            <field name="showall" type="toggle" default="0" label="FORCE_POS"/>
            <field name="showmax" type="showmax" default="6" label="POS_COUNT"/>
        </fields>

If you use 2 complete different positions, like name="overthehead" and name="underheadmodules" the modules rendered correctly

But i used the naming style as seen in template-options.xml (example: maintop, mainbottom)

       <fields name="maintop" type="position" label="MAINTOP_POS" description="LAYOUT_POS_DESC">
            <field name="layout" type="positions" default="3,3,3,3" label="">
                <schemas>1,2,3,4,5,6</schemas>
                <words>2,3,4,5,6,7,8,9,10</words>
            </field>
            <field name="showall" type="toggle" default="0" label="FORCE_POS"/>
            <field name="showmax" type="showmax" default="6" label="POS_COUNT"/>
        </fields>

        <field name="mainbodyPosition" type="positions" default="6,3,3" label="MAINBODY_POS" description="LAYOUT_POS_DESC">
            <schemas>1,2,3,4</schemas>
            <words>sa,sb,sc,mb</words>
            <type>custom</type>
        </field>

        <fields name="mainbottom" type="position" label="MAINBOTTOM_POS" description="LAYOUT_POS_DESC">
            <field name="layout" type="positions" default="3,3,3,3" label="">
                <schemas>1,2,3,4,5,6</schemas>
                <words>2,3,4,5,6,7,8,9,10</words>
            </field>
            <field name="showall" type="toggle" default="0" label="FORCE_POS"/>
            <field name="showmax" type="showmax" default="6" label="POS_COUNT"/>
        </fields>

### Scenario 3

add <position>fullwidthmenu</position> to templateDetails.xml
add no layout to template-options.xml
index.php: Code as above

Same results as in 1 + 2

Re: Adding custom module position cause double rendered modules on site

- ... right now I can only confirm the issue ... workaround is (as you already menioned) to use unique names for the positions.

Re: Adding custom module position cause double rendered modules on site

Posted 10 years 8 months ago
- Found the code where the problem possibly related to:
  Regex in the libraries/gantry/core/gantrytemplate.class.php -> parsePosition() method on initial parsing positions
  
  /** * @param $position * @param $pattern * * @return array */ public function parsePosition($position, $pattern) { $filtered_positions = array(); if (count($this->positions) > 0) { if (!array_key_exists($position, $this->cached_possitions)) { if (null == $pattern) { $pattern = "(-)?"; } $regpat = "/^" . $position . $pattern . "/"; foreach ($this->positions as $key => $value) { if (preg_match($regpat, $value) == 1) { $filtered_positions[] = $value; } } $this->cached_possitions[$position] = $filtered_positions; } } else { return $filtered_positions; } return $this->cached_possitions[$position]; }
  
  If for example parsing the header position, this gets also headertop, headerbottom (if headertop and headerbottom are custom added positions...

Re: Adding custom module position cause double rendered modules on site

Posted 10 years 8 months ago

If i'm right that $pattern is "-a" - "-f", then a tightr regex that match the end of a positionstring too could solve this. I've tested this with latest gantry and epsilon template with modules published in every position and it seems that everything works as intended now.

_{Diff: Line 13 + line 15 - additional regular expression}

	/**
	 * @param $position
	 * @param $pattern
	 *
	 * @return array
	 */
	public function parsePosition($position, $pattern)
	{
		$filtered_positions = array();
		if (count($this->positions) > 0) {
			if (!array_key_exists($position, $this->cached_possitions)) {
				if (null == $pattern) {
					$pattern = "(-)?[a-f]?";
				}
				$regpat = "/^" . $position . $pattern . "$/";
				foreach ($this->positions as $key => $value) {
					if (preg_match($regpat, $value) == 1) {
						$filtered_positions[] = $value;
					}
				}
				$this->cached_possitions[$position] = $filtered_positions;
			}
		} else {
			return $filtered_positions;
		}
		return $this->cached_possitions[$position];
	}

Re: Adding custom module position cause double rendered modules on site

Posted 10 years 8 months ago
- Is this the same problem I am experiencing?
  
  I fixed the file gantrytemplate.class.php with $pattern = "(-)?[a-f]?"; on line 340, but to no avail.
  
  I do not understand the suggested work around.
  
  See www.elliance.nl/paradigm-rocketlauncher_...positions-in-werking

  Have you changed line 342, too?
  
  $regpat = "/^" . $position . $pattern . "$/";

  I'll try to keep my expl. very short
  
  The position with the shortest name have lets say: "ghost copies" in. That is because you have added custom module positions with a name which starts exactly as exsiting positions.
  
  headersuperhero-a ==> One published module, everything is ok
  header ==> Here's the "ghost copy"
  
  feature1-a ==> One published module, everything is ok
  feature ==> Here's the "ghost copy"
  
  custommodulefeature1000-a ==> One published module, everything is ok
  custommodulefeature1000 ==> Here's the "ghost copy"
  custommodulefeature1 ==> Here's also a "ghost copy"
  custommodulefeature ==> Here's also a "ghost copy"
  custommodulefea ==> Here's also a "ghost copy"
  custommodule ==> Here's also a "ghost copy"
  custom ==> Here's also a "ghost copy"
  
  Hope it is only line 342

- Thank you Lahmizar for getting back to me so quickly whilst you are on holiday.
  
  Line 342 did the trick!! I overlooked the dollar sign (how can I overlook that! ).
  
  Enjoy the pool bar!

Re: Adding custom module position cause double rendered modules on site

- Hi All,
  
  I had this same issue with the Anacron 1.2 Template using Gantry v4.1.25 .
  
  I applied Lahmizzar M's fix and things are now working as they should.
  
  Hopefully this fix will make it into the next Gantry update.
  
  Thanks for posting a fix Lahmizzar M. It is very much appreciated.
  
  Kind Regards,
  Tracey

Re: Adding custom module position cause double rendered modules on site

Posted 9 years 11 months ago
- Hi,
  
  I finally just did the update to Gantry v4.1.26 and found this is still an issue in Gantry. After the update my live site was broken in a big way. Thankfully I remembered this issue and found this thread again. I had to re-apply the fix outlined in this thread to fix the problem.
  
  Is there any plans on a permanent fix in the next Gantry update?
  
  Three of us have confirmed this problem going back 9 months and I am very surprised this simple fix hasn't been addressed/implemented by the Gantry Devs yet.
  
  Not to sound like a whiner but if i had forgot about this issue it could have taken hours or even days to find and fix this problem. My site was so broken I would have had to take it down while trying fix it. For me this would have been pretty bad as our site is for a local government entity.
  
  Rockettheme Support, please confirm you have read this and let us know if anything will be done about it.
  
  Thank you
