Introduction
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 | Step | The current step. |
Examples
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;
}
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;
}
