Link Checker
The link checker ensures that all pathways from the current asset to other assets in the system are valid, and is invoked after an edit is committed by clicking the 'Submit' button. If the checker detects any broken links (which includes any relative links, as these are not valid within the CMS), it forwards the user to a page detailing these errors and providing several options for dealing with them.
The first field for each broken link shown on this page gives the value of the link as provided by the user. The second field, 'Content', gives the value of any 'alt' attribute within the <a> element. The third field, 'Spec Violation', details the specific type of violation that caused this link to be detected as broken by the link checker, these can include:
- Invalid Image Link - The source specified for the image was not valid or was relative.
- Broken Link - Either the target given by this link is relative or the link is targeting a nonexistent asset.
The user then has several options for handling each broken link:
- Asset Location - A radio button and file chooser allowing the user to choose an asset within the CMS as the target of the link or source for the image.
- File Upload and Destination - A radio button, file upload input field and chooser allowing the user to choose a file on their computer to upload to the folder specified using the chooser. This file will replace the target of the broken link and the link will be automatically rewritten by the CMS to point to the uploaded resource.
- Ignore - A radio button allowing the user to disregard the broken link.
After deciding how best to handle each broken link, the user then clicks the 'Submit' button. At this point, the link checker rewrites links and uploads files as indicated and commits the user's edits.
