gravityflowpdf_content
The gravityflowpdf_content filter is used to modify the contents the PDF Generator add-on defines via the step settings template before generating the PDF.
Parameters
Parameter | Type | Definition |
---|---|---|
$body | Array | The markup the template from step settings produced with current entry values. |
$file_path | Array | Where the PDF will be generated upon successful completion of the step. |
$entry | Array | The current entry array. |
$step | Gravity_Flow_Step | The current step. |
Examples
Example-1 - Add a custom heading above the PDF template content
add_filter( 'gravityflowpdf_content', 'sh_pdf_content_modify', 10, 4 ); function sh_pdf_content_modify( $body, $file_path, $entry, $step ) { $body = '<h1>Inserting a custom title before template content</h1>' . $body; return $body; }
Example-2 - Prevent the {all_fields} merge tag from shrinking all the text in the table for long tables.
add_filter( 'gravityflowpdf_content', 'sh_pdf_content_modify', 10, 4 ); function sh_pdf_content_modify( $body, $file_path, $entry, $step ) { $body = str_replace( '<table width="99%" border="0" cellpadding="1" cellspacing="0" bgcolor="#EAEAEA"><tr><td>', '', $body ); $body = str_replace( "</td>\r\n </tr>\r\n </table>", '', $body ); return $body; return $body; }
