# Field types

Function change_type() a little difficult to understand, because it uses a specific syntax, which varies depending on the task. Let's try to beat these tasks for conventional groups.

The first three parameters are always the same.

Parameters

  • field - name of the field,
  • type - the desired field type
  • default - (Optional) default value.
  • params_or_attr - (Optional) array with type-parameters and/or html attributes. You can use custom html attributes in most of types.

# 1. Text fields.

This group includes the following types of fields: text, int, float, hidden.

For these types the function of the default value in the third parameter, and the maximum number of characters in the fourth parameter (excluding hidden).

$xcrud->change_type('user_code', 'int', '000', 10); // v1.5 legacy
$xcrud->change_type('user_code', 'int', '000', array('maxlength'=>10)); // v1.6

IMPORTANT

Use fields() and pass_var() methods to hide fields and put custom data in your table.

# 2. Multi-line text fields.

This group includes the following types of fields: textarea, texteditor.

This types no need any additional parameters.

$xcrud->change_type('user_desc', 'textarea');

# 3. Date fields.

This group includes the following types of fields: date, datetime, time, year, timestamp.

These types of fields will only accept the default value in the third parameter.

$xcrud->change_type('created', 'datetime', '2012-10-22 07:01:33');

Date range can be used with date type:

$xcrud->change_type('created', 'date', '', array('range_end'=>'end_date')); // this is start date field and it points to end date field
$xcrud->change_type('created', 'date', '', array('range_start'=>'start_date')); // this is end of range date and it points to the start date range date

This will create relation between two date fields

# 4. Lists.

This group includes the following types of fields: select, multiselect, radio, checkboxes

These types of fields are set to default in the third argument, and a list of available values, separated by commas, in the second parameter. multiselect can contain several values ​​by default.

$xcrud->change_type('adm_email', 'select', 'email2@ex.com', 
	'email1@ex.com, email2@ex.com, email3@ex.com, email4@ex.com, email5@ex.com');
$xcrud->change_type('fav_color', 'multiselect', 'black, white', 
	'red, blue, yellow, green, black, white');
 
// v1.6 new syntax
$xcrud->change_type('fav_color', 'multiselect', 'black, white',  
	array('values' => 'red, blue, yellow, green, black, white')
);

You can show optgroups in dropdowns. Just us multi-dimensional array:

$xcrud->change_type('country', 'select', '', 
	array('values' => array(
		'Europe' => array('UK' => 'United Kindom', 'FR' => 'France'), 
		'Asia' => array('RU' => 'Russia', 'CH' => 'China'))
));

Checkboxes

$xcrud->change_type('bool', 'checkboxes', '', array('values' => 
	array(1 => 'Yes', 0 => 'No'))
);

Radio buttons

$xcrud->change_type('bool', 'radio', '', array('values' => 
	array(1 => 'True', 0 => 'False'))
);

# 5. Password.

This group includes the following types of fields: password.

Takes the type of hashing in the third parameter (e.g. md5 or sha1 or sha256... , leave blank if you do not want to use hashing) and the maximum number of characters in the fourth. The peculiarity of this field is that it does not load the values ​​and does not store the null value (not allowing you to change the previous one to null). This is due to the fact that passwords are usually encrypted or hashed before being stored in the database.

$xcrud->change_type('user_key', 'password', '', 32);
$xcrud->change_type('user_pass', 'password', 'sha256', 8);
// attributes example
$xcrud->change_type('user_pass', 'password', 'md5', array('maxlength'=>10,'placeholder'=>'enter password'));

# 6. Upload.

This group includes the following types of fields: file, image.

Takes the path to the upload folder (must exist and be writable) in the third parameter and configuration array in the fourth.

For all uploaded files xCRUD creates a unique name to avoid overwriting, but you can cancel the renaming. In this case, the file name will be brought to the alpha-numeric pattern.

$xcrud->change_type('attach', 'file', '', array('not_rename'=>true));

You can resize the uploaded image, and crop them at different proportions.

$xcrud->change_type('photo','image','',array('width'=>300)); // resize main image
$xcrud->change_type('photo','image','',array('width'=>300, 'height'=>300, 'crop'=>true)); // auto-crop
$xcrud->change_type('photo','image','',array('manual_crop'=>true)); // crop it as you want

You can create a preview picture for your image to be stored in that same folder, and a marker will differ at the end of the name. You can also specify the size of thumbnails, resize method and subfolder.

NOTE

'Manual crop' will crop thumbnails in same proportion as main image

You can add any number of thumbs, you must create subarray in thumbs array for each thumbnail

$xcrud->change_type('photo','image','',array(
    'thumbs'=>array(
        array('width'=> 50, 'marker'=>'_small'),
        array('width'=> 100, 'marker'=>'_middle'),
        array('width' => 150, 'folder' => 'thumbs' // using 'thumbs' subfolder
    )
));

You can save your image as a binary string in the database. For this field in your database must be of type BLOB, MEDIUMBLOB or LONGBLOB. Thumbnail creation in this case is not available. If you do not know how to extract data from these fields, it is better use the normal load.

$xcrud->change_type('photo','image','',array('blob'=>true));
