Placeholder Variables
---------------------
What is a placeholder in the datagrid control?
A placeholder is a just the same as a variable. It is a name and references a column in a particular row.
For exampe; lets say you had a Pets table with PetName, PetAge and PetComment columns.
You can reference other columns in the PetComment by placing percent symbols (%) around the column name you are specifying.
If the primary key is set during the setQuery method, you can use %_P% as a placeholder for the table's primary key.
Where can I use this?
This can be on the database or scripted.
This can be used in column types criteria and criteria_2 param. Look below on TYPE_IMAGE and TYPE_CUSTOM for more examples.
Column Types and Usage
----------------------
A quick overview of the available column types. I learn best by examples so I've included plenty for you.
TYPE_ONCLICK
-Sets a "onclick" call on a cell value
-e.g: $db->setColumnType('FirstName', EyeDataGrid::TYPE_ONCLICK, "alert('Hello?')");
TYPE_HREF
-Sets a href link on a cell value
-e.g: $db->setColumnType('FirstName', EyeDataGrid::TYPE_HREF, "http://www.google.com");
TYPE_DATE
-Format a date
-e.g: $db->setColumnType('Birthday', EyeDataGrid::TYPE_DATE, "M d, Y", true); // Converts to a timestamp and then to the formatted date
-e.g: $db->setColumnType('Birthday', EyeDataGrid::TYPE_DATE, "M d, Y"); // Converts formatted date from a timestamp
TYPE_IMAGE
-Changes a column's values to a image
-e.g: $db->setColumnType('Photo', EyeDataGrid::TYPE_IMAGE, "/images/photos/%LastName%.png");
TYPE_ARRAY
-Maps a value to a key in an array
-e.g: $db->setColumnType('Gender', EyeDataGrid::TYPE_ARRAY, array('f' => 'Female', 'm' => 'Male'));
TYPE_CHECK
-Converts a cell to a checkmark when the value is "1", "true", "yes" or value matches 3rd passed value
-e.g: $db->setColumnType('Single?', EyeDataGrid::TYPE_CHECK);
-e.g: $db->setColumnType('Single?', EyeDataGrid::TYPE_CHECK, 'legs');
TYPE_PERCENT
-Converts a value to a percent as a whole number
-e.g: $db->setColumnType('Score', EyeDataGrid::TYPE_PERCENT); // Value is already in percent
-e.g: $db->setColumnType('Score', EyeDataGrid::TYPE_PERCENT, true); // Value is converted from decimal format when 3rd param is true
-e.g: $db->setColumnType('Score', EyeDataGrid::TYPE_PERCENT, true, array('Back' => 'red', 'Fore' => 'black')); // Adds bars whose width represents the percent, colors are specified as 'Back' and 'Fore'
TYPE_DOLLAR
-Converts a value to the a currency. Always rounded to 2 decimal places
-e.g: $db->setColumnType('Price', EyeDataGrid::TYPE_DOLLAR);
TYPE_CUSTOM
-Convert value to a custom value
-e.g: $db->setColumnType('School', EyeDataGrid::TYPE_CUSTOM, 'I go to %CollegeName% in %City%, %Province%'); // Converts a cell to "I go to..". Placeholders are replaced with the value in that row's column
TYPE_FUNCTION
-Sends a value (or values) to a user specified function
-e.g: $db->setColumnType('Password', EyeDataGrid::TYPE_FUNCTION, 'md5', '%Password%'); // Value is sent to the md5 function and return is printed in the cell
-e.g: $db->setColumnType('Password', EyeDataGrid::TYPE_FUNCTION, 'make_hash', '%Password%'); // Value is sent to the make_hash user function and return is printed in the cell
-e.g: $db->setColumnType('Password', EyeDataGrid::TYPE_FUNCTION, 'generate_key', array('%Username%', '%Password%')); // To pass multiple params to the user function use an array
