getMenu

Syntax

string getMenu(
    string $selectName,
    optional mixed $defaultValue=false,
    optional mixed $blankFirstItem=true,
    optional bool $multiple=false,
    optional int $numberOfRows=0,
    optional string $optionalAttributes='',
    optional bool $compareAgainstFirstCol=true
    )

Description

The function getMenu() generates an HTML SELECT tag string from a recordset, and returns the string.

If the recordset has a single column, the option values and descriptions are the same. If it has 2 columns, the first one is the description and the second is the value. By default, the 2nd column is matched against $defaultValue, if provided.

Any extra column beyond the first two will be discarded.

Until ADOdb 5.20.13, this method required that ADODB_FETCH_MODE be set to ADODB_FETCH_NUM prior to execution of the SQL statement that will provide the recordset. Starting with 5.20.14, all fetch modes are supported

Parameters

$selectName

name of SELECT tag

$defaultValue

The value to highlight. Use either a string for a single value to match, or a numeric array if a multiselect box is going to be built and there are multiple matching defaults.

$blankFirstLine

This parameter has the following available options:

true (default) - creates an empty <option></option> tag
false - does not creates an empty <option></option> tag
string value - creates an <option value=“”>STRING</option> tag
string value format value:description - creates an <option value='value'>description</option> tag

$multiple

Set true to create a multi-select box

$numberOfRows

Number of rows to show for multi-select box. If. a multi-select box is not created, this field has no meaning.

$optionalAttributes

Additional attributes to defined for SELECT tag, useful for holding javascript onChange='…' handlers or class information. Note that by default, the select box is generated without an id, so this should be included here.

$compareAgainstFirstCol

If we have 2 columns, by default the default value is located by matching against the 2nd column (the value). By setting this flag to false, we can locate the selected option by matching against the 1st column (the description). This works even if the list of selected items is an array
