    Hi!

    First thank you for your great, I read doc on this since a day and I’m incredibly amazed by your work on this!
    And with your great support, I found solutions about almosts of my questions.

    I still have few questions.
    Can we modify the content of all cells in a column via php hook ?

    Concrete example1:
    I have a column with URL to image file in plain text.

    https://mywebsite.com/image.png

    I want each linked to be parsed so that it become

    [shortcode attribute="https://mywebsite.com/image.png"]Click me[/shortcode]

    EDIT:
    Concrete example2:
    Use the value of of another column to modify the values of one column.
    If there is a URL Title column and a URL column then transform the column link into [shortcode attribute=”URl column”]URl Title[/shortcode]

    Concrete example3:
    Parse comma separated value of cell
    Exemple: Original cell = https://url.com/image1.gif, https://url.com/image1.gif
    Modified cell = `
    [shortcode attribute=”https://url.com/image1.gif”%5DClick me[/shortcode], [shortcode attribute=”https://url.com/image2.gif”%5DClick me[/shortcode]
    `

    Is that possible ?
    Can this shortcode be then interpreted by an other plugin ?
    Maybe with the PHP in cells plugin and do_shortcode ?

    Thank you again for your support!

    Hi,

    thanks for your post, and sorry for the trouble.

    Using plugin filter hooks should indeed be the best method here. If you want to access/modify single cells, the tablepress_cell_content hook should be the best. For combining the information from cells/columns, tablepress_table_render_data is the best. Both are defined in the classes/class-render.php file.

    Using the PHP in tables Extension is not necessary here, as the PHP code is in your own plugin with this approach. If you use the tablepress_table_render_data filter hook, you can indeed simply use do_shortcode() yourself. But then you could also just call the Shortcode handler function directly.

    Is there any infos online our all infos are in the class-render.php file ?

    Hi,

    the tablepress_table_render_data hook will give you the entire table as a two-dimensional PHP array. With a custom loop, you can go through all cells of a column there.

    Unfortunately, there’s no direct documentation on these filter hooks, but the actual code should be a good way to learn.

    And thanks for the rating, I really appreciate it!

    Meanwhile, the Automatic URL conversion | TablePress extension will be perfect!

    Marked as resolved!

    Hi,

    great! Yes, that should already be enough for the task of converting the URLs. Otherwise, it’s also a good example for how to use the tablepress_cell_content filter hook.

    Best wishes,
    Tobias
