Joomla text Form Field Type

The text form field type provides a text box for data entry. If the field has a value saved, this value is displayed when the page is first loaded. If not, the default value (if any) is selected.

XML Field Definition

<field
 name="mytextvalue" 
 type="text" 
 default="Some text" 
 label="Enter some text" 
 description="" 
 size="10" />

Use the integer filter to ensure that letters get stripped when the form is processed.

<field 
 name="myintvalue" 
 type="text" 
 default="" 
 label="Enter some text" 
 description="Enter some description" 
 filter="integer" />

Use the raw filter to ensure that html code is preserved when the form is processed.

<field 
 name="myhtmlvalue" 
 type="text" 
 default="" 
 label="Enter some text" 
 description="Enter some description" 
 filter="raw" />
