Max length of text field

Question

How can I increase the max lenght of Tab-Title ?

Answer 1

With module: Title you can convert title to field and then you can change the field length

For title-tab goto: admin/structure/types/manage choose your content type and then manage fields edit your field

Answer 2

Maxlength

Maxlength allows you to set maximum length of any field on any form making use of the form API. This includes fields created using the UI. (Example: any text field on a node) In D6 Maxlength allows you to set maximum lengths to the body, title and CCK textfields of any content type (node).

By custom

I got the solution for my question. I have create a custom_field_length.module. In custom_field_length module I have add this code.

function custom_field_length_change_text_field_max_length($field_name, $new_length) {
 $field_table = 'field_data_' . $field_name;
 $field_revision_table = 'field_revision_' . $field_name;
 $field_column = $field_name . '_value'; 

 // Alter value field length in fields table
db_query("ALTER TABLE `{$field_table}` CHANGE `{$field_column}` `{$field_column}` VARCHAR( {$new_length} )");

// Alter value field length in fields revision table
db_query("ALTER TABLE `{$field_revision_table}` CHANGE `{$field_column}` `{$field_column}` VARCHAR( {$new_length} )");

// Update field config with new max length
$result = db_query("SELECT CAST(`data` AS CHAR(10000) CHARACTER SET utf8) FROM `field_config` WHERE field_name = '{$field_name}'");
$config = $result->fetchField();
$config_array = unserialize($config);
$config_array['settings']['max_length'] = $new_length;
$config = serialize($config_array);
db_update('field_config')
    ->fields(array('data' => $config))
    ->condition('field_name', $field_name)
    ->execute();
}

function custom_field_length_update_8002() {
  custom_field_length_change_text_field_max_length('field_tab_title', 255);
}

After enable module I will run update.php after that my field size is increase to 255.
