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

}

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.

[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.
