Methods

action_initialize()

Method called before the module is enabled for the first time. @param boolean -- returns true on success. false on error.

• Defined in i2ce/modules/Forms/modules/FormLimits/lib/I2CE_Module_FormLimits.php on line 39
• Signature: public function action_initialize()

checkLimit()

Checks a limit expression for a field based on limit data

• Defined in i2ce/modules/Forms/modules/FormLimits/lib/I2CE_Module_FormLimits.php on line 101
• Signature: public function checkLimit($formObj,$limit_data)
• Parameters:
  • I2CE_Form $formObj
  • mixed $limit_data array.
    • Default Value: array()
• Returns: boolean
  or null on failure

checkWhereClause()

The implementation of the fuzzy method to check that a where clause is satisfied by the given form Walks down the where clause data create the WHERE query it defined.

• Defined in i2ce/modules/Forms/modules/FormLimits/lib/I2CE_Module_FormLimits.php on line 144
• Signature: public function checkWhereClause($formObj,$expr)
• Parameters:
  • I2CE_Form $formObj
  • mixed $expr
    array or class implementing ArrayAccess, Iterator, and Countable (e.g. MagicDataNode) . the where data.
• Returns: boolean,
  null on failure

createCheckFunction()

Create a check function based on the where data. The function takes on argument which is an array indexed by the field names and with values the value of the field. @param I2CE_Form $form @param callback $field_refernece_callback. A callback function whose first arguement is the form, the second arguements is the field and which returns the way the field value should be references as a field. If the callback is null (the default) then the reference used is $data["$field']

• Defined in i2ce/modules/Forms/modules/FormLimits/lib/I2CE_Module_FormLimits.php on line 240
• Signature: public function createCheckFunction($formObj,$expr,$field_reference_callback,$func_args)
• Parameters:
  • $formObj
  • mixed $expr
    array or class implementing ArrayAccess, Iterator, and Countable (e.g. MagicDataNode) . the where data.
  • $field_reference_callback
    • Default Value: null
  • string $func_args
    Defaults to $data
    • Default Value: '$data'
• Returns: false
  on failure a funciton on sucess.

createCheckFunctionString()

Create a check function boolean expression based on the where data. The function takes on argument which is an array indexed by the field names and with values the value of the field. @param I2CE_Form $form @param callback $field_refernece_callback. A callback function whose first arguement is the form, the second arguements is the field and which returns the way the field value should be references as a field. If the callback is null (the default) then the reference used is $data["$field']

• Defined in i2ce/modules/Forms/modules/FormLimits/lib/I2CE_Module_FormLimits.php on line 272
• Signature: public function createCheckFunctionString($formObj,$expr,$field_reference_callback)

  • $field_reference_callback
    • Default Value: null
• Returns: false
  on failure a string to which can be evalued as true/false on success.

createCheckLimitString()

    • Default Value: null
• Returns: string
  or false on failure

generateLimit()
