TYPO3 - not showing up my contents after creating custom content element-CodePudding

I created a custom content element on my TYPO3 ver. 10.4.21 and I could show a HTML-file (in /Resources/Private/Templates/ContentElements/NewContentElement.html) once, but after changing a tt_content.php file I couldn't show up my content any more.... (I wanted to configrate some field on a edit page after creating the content element.)

My question is in this case:

Does Symfony Expression Language do something?
cache?

My template path is following:

lib.contentElement {
  templateRootPaths {
    100 = EXT:mein_projektarbeit/Resources/Private/Templates/
  }
  partialRootPaths {
    100 = EXT:mein_projektarbeit/Resources/Private/Partials/
  }
  layoutRootPaths {
    100 = EXT:mein_projektarbeit/Resources/Private/Layouts/
  }
}

In template I can see this path:

[100] = EXT:mein_projektarbeit/Resources/Private/Templates/ # register a content elements # # Path to Templates, Partials, Layouts

I could show my contents up from my NewContentElement.html, so I think that the template path is correct.

Tried:

I activated and deactivate my extension and after that I cleared the cashes. Also, the extension is included static in root(Template > include > my extension on the left side) again. But I can't see my content any more, even if my html-file (NewContentElements.html) is in mein_projektarbeit/Resources/Private/Templates/.

Is there anything to do for this problem?

I tried to make a new custom content Element with another domain and I could make it. Is it just a one time possible to make a custom content element in a domain? I can't believe it, but it's not working anymore with my same domain. But I want to avoid to make one more Domain for this.... Please help me if you can.

MEMO: SQL-code on debug, if I show my main page. uid=22 is right.

SELECT * FROM `pages` WHERE (`uid` = 2) AND (((`pages`.`deleted` = 0) AND (`pages`.`t3ver_state` <= 0) AND (`pages`.`t3ver_wsid` = 0) AND (`pages`.`t3ver_oid` = 0) AND (`pages`.`hidden` = 0) AND (`pages`.`starttime` <= 1637053080) AND ((`pages`.`endtime` = 0) OR (`pages`.`endtime` > 1637053080))) AND (`pages`.`doktype` <> 255)) AND (((`pages`.`fe_group` = '') OR (`pages`.`fe_group` IS NULL) OR (`pages`.`fe_group` = '0') OR (FIND_IN_SET('0', `pages`.`fe_group`)) OR (FIND_IN_SET('-1', `pages`.`fe_group`))))

Also, If I check my databank, tstamp: 1636985310 crdate: 1636705565 sys_lastchanged: 1636985310 I changed the sys_lanstchanged from 1636985310 to 0, but it hasn't changed anything.

And in sys_template in databank: include_static_file: EXT:fluid_styled_content/Configuration/TypoScript/,EXT:fluid_styled_content/Configuration/TypoScript/Styling/,EXT:mein_projektarbeit/Configuration/TypoScript

Maybe, it's not related to the content element anymore? Because another content elements which I made with a regular text element doesn't show up. The fully page doesn't show up on my website and any errors don't come up.

Thank you for your help.

CodePudding user response：

your configuration states:

lib.contentElement {
  templateRootPaths {
    100 = EXT:mein_projektarbeit/Resources/Private/Templates/
  }

your template file is at EXT:mein_projektarbeit/Resources/Private/Templates/ContentElements/

are you sure your templates are called with the complete relative path (ContentElements/NewContentElement)?

another reason for errors: do you have the correct spelling?

CodePudding user response：

Thank you everyone.

I found my mistake now! There ware no code in Default.html in \Resouces\Private\Layout\Page\Default.html. If I wrote my codes, the contents of NewContentElements.html is also shown up!

I'm so sorry for that and thank you all.
