Search for string part per TypoScript

To search a string part (needle) in string (haystack), you can easily use the PHP strpos function. But this function doesn’t exist in TypoScript.

The following TypoScript return true if the needle is found in the haystack. This can be used in an if condition.

cObject = COA
cObject {
  1 = LOAD_REGISTER
  1 {
    # search for http (or https).
    needle = http

    # search in
    haystack.field = header_link

    # split haystack by the needle
    # result is a haystack without a needle, if found
    findNeedleInHaystack.cObject = TEXT
    findNeedleInHaystack.cObject {
      data = REGISTER:haystack
      split.token.data = REGISTER:needle
    }
  }

  # compare REGISTER:haystack and result of REGISTER:findNeedleInHaystack
  # if both are the same, nothing was found
  10 = TEXT
  10 {
    # true will be returned, if the needle was found inside haystack
    value = true

    if {
      value.data = REGISTER:haystack
      equals.data = REGISTER:findNeedleInHaystack

      # if the same, then negate the return value
      negate = 1
    }
  }
}

cObject = COA

cObject {

1 = LOAD_REGISTER

1 {

# search for http (or https).

needle = http

# search in

haystack.field = header_link

# split haystack by the needle

# result is a haystack without a needle, if found

findNeedleInHaystack.cObject = TEXT

findNeedleInHaystack.cObject {

data = REGISTER:haystack

split.token.data = REGISTER:needle

}

# compare REGISTER:haystack and result of REGISTER:findNeedleInHaystack

# if both are the same, nothing was found

10 = TEXT

10 {

# true will be returned, if the needle was found inside haystack

value = true

if {

value.data = REGISTER:haystack

equals.data = REGISTER:findNeedleInHaystack

# if the same, then negate the return value

negate = 1

}

The above COA will return true if http is found in the header_link field. I used this to add ATagParams for external link, in assumption that link with http(s) is an external link.

ATagParams = class="external"
ATagParams.if {
  cObject = COA
  cObject {
    // the strpos function
  }
}

ATagParams = class="external"

ATagParams.if {

cObject = COA

cObject {

// the strpos function

}

Adding javascript: in href using TYPO3 RTE

The link wizard is a great tool for normal TYPO3 user to add link (internal, external, or email link). But what if a javascript function needs to be triggered manually by clicking a link? you can make an onClick event listener to achieve this. But in RTE you can also adds javascript:someFunction(); as href parameter.

To do this, switch to text mode in RTE by clicking the <> button and put your link manually. Following parameters need to be added manually:

 data-htmlarea-external="1" rtekeep="1

1	data-htmlarea-external="1" rtekeep="1

so should the link looks like

<a href="javascript:someFunction();" data-htmlarea-external="1" rtekeep="1>Javascript Text</a>

1	<a href="javascript:someFunction();" data-htmlarea-external="1" rtekeep="1>Javascript Text</a>

Automatically apply PSR-2 coding style

*UPDATE*

In version 2 of php_cs_fixer some parameters and rules are renamed. Upgrade guide can be see on their Github page. This how-to is accordingly updated.

Applying PSR-2 coding style manually is really no fun and wasting time. A short visit in Github and there’s a tool which detects and fixes the coding style. The tool is called php-cs-fixer.

I’ll show you how to get the tool and use it to easily reformat all PHP file in project.

Fail downloading file on Android

How hard is it, to write a PHP script to allow user to download a file? really easy, one would say. Just send the appropriate HTTP header and echo the file content.

<?php
  header('Content-type: application/force-download');
  header('Content-Disposition: attachment; filename="test.txt"');
  echo(file_get_content('/path/to/file'));
?>

<?php

header('Content-type: application/force-download');

header('Content-Disposition: attachment; filename="test.txt"');

echo(file_get_content('/path/to/file'));

Basically that’s all I need to force download per PHP. But somehow Android stock browser (Chrome) only downloads and creates a 0 kB file. Other browser (tested with Firefox on Android) saves the file correctly.

What does happen here?

Extbase and RealURL

another day, another problem. Extbase is becoming main framework for TYPO3 extension, because it’s really easy to create a frontend plugin to show (listing or detail view) of a records. Since it’s MVC framework, Extbase create a complex URL for each record.

http://domain.tld/pageName/?tx_extension_plugin[action]=show&tx_extension_plugin[controller]=controllerName&tx_extension_pluginName[param]=9

how to short this?

Standalone view in extbase

Usually a view in extbase is always called from a controller. but what if, an action in your controller is called as an eID and only parts of the template needs to be rendered? Partial is an option, but I have a code snippet, which uses the

TYPO3\\CMS\\Fluid\\View\\StandaloneView

1	TYPO3\\CMS\\Fluid\\View\\StandaloneView

class.

add class to link in RTE

It’s might be a simple problem, but yet it’s really hard to find the correct solution. Although the solution is a simple one.

Using any of the CSS frameworks out there, you can easily create a button, even from a link, just by adding a class. The problem is, how you can put this class in RTE, so that the editor can easily choose which button class should be used.

redirect URL to lowercase

Using the realurl extension TYPO3 generate human-readable URL. If the visitor visits the page using uppercase of the URL, TYPO3 can generate the page (HTTP 200). if a search bot (Google) found this URL and indexed it, Google will declare the page as “double content” and punishes your page rank. How do we deal with this? Continue reading redirect URL to lowercase

[TYPO3] Redirect to last page

Problem of the week:

you have a password protected pages on your TYPO3 site. If you spread the URL of the pages and other user will be shown the login page, if they call the URL. Problem will be, after logging in, the user is not redirected to the last page, which they call.

The felogin extension of TYPO3 supports 6 type of redirect after login:

defined by usergroup record
defined by user record
TypoScript or Flexform of the felogin extension
GET/POST-Parameter
Referer
Domain entries

The solution is the “referer” redirection. The question is how. This is where we use the fabulous TypoScript.

[loginUser = ]
page.headerData.666 = COA_INT
page.headerData.666 {
	10 = TEXT
	10 {
		typolink {
			parameter = xxx
			additionalParams {
				data = getIndpEnv:TYPO3_REQUEST_URL
				rawUrlEncode = 1
				wrap = &amp;referer=|
			}
			returnLast = url
		}
		wrap = &lt;meta http-equiv="refresh" content="0; URL=/|"/&gt;
	}
}
[end]

[loginUser = ]

page.headerData.666 = COA_INT

page.headerData.666 {

10 = TEXT

10 {

typolink {

parameter = xxx

additionalParams {

data = getIndpEnv:TYPO3_REQUEST_URL

rawUrlEncode = 1

wrap = &referer=|

}

returnLast = url

}

wrap = <meta http-equiv="refresh" content="0; URL=/|"/>

}

[end]

This TypoScript creates a redirect per meta tag (see wrap), but to which URL. The magic happens in the typolink function. xxx is your login page. The GET parameter “referer” will have the value of the last page, which the user visited.

The magic does not end here. You have to set to “referer” redirect in the flexform of the felogin extension.

so that’s all.. hope this could be help.

Cheers
