Configuration

You can find the standard configuration in EXT:linkvalidator/Configuration/page.tsconfig.

This may serve as an example on how to configure the extension for your needs.

Note

When checking for broken links in the TYPO3 backend module or the corresponding Scheduler task, the page TSconfig of the selected start page is also applied to all subpages - when checking recursive. In case subpages should behave differently and therefore contain a different LinkHandler configuration, they must be checked individually.

Minimal configuration

It is recommended to at least fill out httpAgentUrl and httpAgentEmail. The latter is only required if $GLOBALS['TYPO3_CONF_VARS']['MAIL']['defaultMailFromAddress'] is not set.

mod.linkvalidator.linktypesConfig.external.httpAgentUrl =
mod.linkvalidator.linktypesConfig.external.httpAgentEmail =

Reference

You can set the following options in the TSconfig for a page (for example the root page) and override them in user or groups TSconfig. You must prefix them with mod.linkvalidator, for example mod.linkvalidator.searchFields.pages = canonical_link.

searchFields.[key]

Property

searchFields.[key]

Data type

string

Description

Comma separated list of table fields in which to check for broken links. LinkValidator only checks fields that have been defined in searchFields.

LinkValidator ships with sensible defaults that work well for the TYPO3 core, but additional third party extensions are not considered.

Warning

Currently, LinkValidator will only detect links for fields if the TCA configuration meets one of these criteria:

at least one t3tca:columns-input-properties-softref
type is set to link

For this reason, it is currently not possible to check for pages.media. This will be fixed in the future.

Examples for working fields:

pages.canonical_link ('type' => 'link')
pages.url ('softref' => 'url')
sys_file_reference.link ('type' => 'link')

Example for not working fields:

pages.media ('type' => 'file')

Example

# Only check for "bodytext" in "tt_content":
tt_content = bodytext

Default

pages = media,url
tt_content = bodytext,header_link,records

linktypes

Property

linktypes

Data type

string

Description

Comma separated list of link types to check.

Possible values:

db: Check links to database records.

file: Check links to files located in your local TYPO3 installation.

external: Check links to external URLs.

This list may be extended by other extensions providing a custom linktype implementation.

Warning

External links can lead to some known issues.

Default

db,file,external

linktypesConfig.external.httpAgentName

Property: linktypesConfig.external.httpAgentName
Data type: string
Description: Add descriptive name to be used as 'User-Agent' header when crawling external URLs.
Default: TYPO3 LinkValidator

linktypesConfig.external.httpAgentUrl

Property: linktypesConfig.external.httpAgentUrl
Data type: string
Description: Add URL to be used in 'User-Agent' header when crawling external URLs.
Default: (empty string)

linktypesConfig.external.httpAgentEmail

Property: linktypesConfig.external.httpAgentEmail
Data type: string
Description: Add descriptive email used in 'User-Agent' header when crawling external URLs.
Default: $GLOBALS['TYPO3_CONF_VARS']['MAIL']['defaultMailFromAddress']

checkhidden

Property: checkhidden
Data type: boolean
Description: If set, disabled pages and content elements are checked for broken links, too.
Default: 0

showCheckLinkTab

Property: showCheckLinkTab
Data type: boolean
Description: If set, the backend module shows a "Check Links" tab, which you can use to perform the checks on demand.

The Check links tab is visible

Note

Depending on the number of page levels to check and on the number of links in these pages, this check can take some time and need some resources. For large sites it might therefore be advisable to hide the tab.

Note

LinkValidator uses a database table to store information about the broken links, which it found in your website. If showCheckLinkTab is set to 0, you must use the Scheduler task provided by LinkValidator to update this information.
Default: 1

actionAfterEditRecord

Property

actionAfterEditRecord

Data type

string

Default

recheck

Possible values

recheck | setNeedsRecheck

Description

After a record is edited, the list of broken links may no longer be correct, because broken links were changed or removed or new broken links added. Due to this, the list of broken links should be updated.

Possible values are:

recheck: The field is rechecked. (Warning: an RTE field may contain a number of links, rechecking may lead to delays.)
setNeedsRecheck: The entries in the list are marked as needing a recheck

mail.fromname

Property

mail.fromname

Data type

string

Description

Set the from name of the report mail sent by the cron script.

Default

Install Tool

defaultMailFromName

mail.fromemail

Property

mail.fromemail

Data type

string

Description

Set the from email of the report mail sent by the cron script.

Default

Install Tool

defaultMailFromAddress

mail.replytoname

Property: mail.replytoname
Data type: string
Description: Set the replyto name of the report mail sent by the cron script.

mail.replytoemail

Property: mail.replytoemail
Data type: string
Description: Set the replyto email of the report mail sent by the cron script.

mail.subject

Property: mail.subject
Data type: string
Description: Set the subject of the report mail sent by the cron script.
Default: TYPO3 LinkValidator report

Hint

The following are advanced settings. In most cases, the defaults should be sufficient.

linktypesConfig.external.headers

Property: linktypesConfig.external.headers
Data type: array
Description: Additional set of HTTP headers to be passed when crawling URLs.
Default: (empty array)

linktypesConfig.external.method

Property

linktypesConfig.external.headers

Data type

array

Description

This specified which method is used for crawling URLs. By default, we use HEAD (which falls back to GET if HEAD fails).

You can use GET as an alternative, but keep in mind that HEAD is a lightweight request and should be preferred while GET will fetch the remote web page (within the limits specified by range, see next option).

"The HEAD method is identical to GET except that the server MUST NOT return a message-body in the response." (w3 RFC2616).

Default

HEAD

linktypesConfig.external.range

Property: linktypesConfig.external.headers
Data type: string
Description: Additional HTTP request header 'Range' to be passed when crawling URLs. Use a string to specify the range (in bytes).
Default: 0-4048

linktypesConfig.external.timeout

Property

linktypesConfig.external.timeout

Data type

integer

Description

HTTP request option. This is the total timeout of the request in seconds.

If set, this overrides the timeout in $GLOBALS['TYPO3_CONF_VARS']['HTTP']['timeout'] which defaults to 0.

Important

A value of 0 means no timeout, which may result in the request not terminating in some edge cases and can also result in Scheduler tasks to run indefinitely. There is an additional $GLOBALS['TYPO3_CONF_VARS']['HTTP']['connect_timeout'] which defaults to 10 seconds, but this may not be enough to lead to a request terminating in some edge cases.

Default

20

Example

mod.linkvalidator {
        searchFields {
                pages = url,canonical_link
                tt_content = bodytext,header_link,records
        }
        linktypes = db,file,external
        checkhidden = 0
        mail {
                fromname = TYPO3 LinkValidator
                fromemail = no_reply@mydomain.com
                replytoname =
                replytoemail =
                subject = TYPO3 LinkValidator report
        }
        external {
                httpAgentUrl = https://example.com/info.html
                httpAgentEmail = info@example.com
        }
}
