defineContentAttribute()

Returns the field’s content attribute config.

The attribute config returned by this method is used to define two things:

• This field’s attribute in {@link ContentModel::defineAttributes()}.
• This field’s column in the craft_content table.

The method can return a string (e.g. AttributeType::Number) or an array with additional settings (e.g. array(AttributeType::Number, 'min' => 0, 'max' => 100, 'decimals' => 2)) if the attribute type’s default settings defined by {@link ModelHelper::$attributeTypeDefaults} aren’t good enough.

If you return AttributeType::Mixed, your field type can work with array data, and it will automatically be JSON-encoded when getting saved to the database, and automatically JSON-decoded when getting fetched from the database. All your field type will ever see is the actual array.

If the field type is storing its data in its own table and doesn’t need a column in the craft_content table, this method should return false. You can then save your data manually from {@link onAfterElementSave}.

IFieldType::defineContentAttribute()

IFieldType::defineContentAttribute()

View source (opens new window)

Returns

mixed – The field’s content attribute config, or false if it’s storing data in its own table.

Signature

public mixed defineContentAttribute ( )

getSettingsHtml()

Returns the component’s settings HTML.

An extremely simple implementation would be to directly return some HTML:

return '<textarea name="foo">'.$this->getSettings()->foo.'</textarea>';

For more complex settings, you might prefer to create a template, and render it via {@link TemplatesService::render()}. For example, the following code would render a template loacated at craft/plugins/myplugin/templates/_settings.html, passing the settings to it:

return craft()->templates->render('myplugin/_settings', array(
    'settings' => $this->getSettings()
));

If you need to tie any JavaScript code to your settings, it’s important to know that any name= and id= attributes within the returned HTML will probably get {@link TemplatesService::namespaceInputs() namespaced}, however your JavaScript code will be left untouched.

For example, if getSettingsHtml() returns the following HTML:

<textarea id="foo" name="foo"></textarea>

<script type="text/javascript">
    var textarea = document.getElementById('foo');
</script>

…then it might actually look like this before getting output to the browser:

<textarea id="namespace-foo" name="namespace[foo]"></textarea>

<script type="text/javascript">
    var textarea = document.getElementById('foo');
</script>

As you can see, that JavaScript code will not be able to find the textarea, because the textarea’s id= attribute was changed from foo to namespace-foo.

Before you start adding namespace- to the beginning of your element ID selectors, keep in mind that the actual namespace is going to change depending on the context. Often they are randomly generated. So it’s not quite that simple.

Thankfully, {@link TemplatesService} provides a couple handy methods that can help you deal with this:

• {@link TemplatesService::namespaceInputId()} will give you the namespaced version of a given ID.
• {@link TemplatesService::namespaceInputName()} will give you the namespaced version of a given input name.
• {@link TemplatesService::formatInputId()} will format an input name to look more like an ID attribute value.

So here’s what a getSettingsHtml() method that includes field-targeting JavaScript code might look like:

public function getSettingsHtml()
{
    // Come up with an ID value for 'foo'
    $id = craft()->templates->formatInputId('foo');

    // Figure out what that ID is going to be namespaced into
    $namespacedId = craft()->templates->namespaceInputId($id);

    // Render and return the input template
    return craft()->templates->render('myplugin/_fieldinput', array(
        'id'           => $id,
        'namespacedId' => $namespacedId,
        'settings'     => $this->getSettings()
    ));
}

And the _settings.html template might look like this:

<textarea id="{{ id }}" name="foo">{{ settings.foo }}</textarea>

<script type="text/javascript">
    var textarea = document.getElementById('{{ namespacedId }}');
</script>

The same principles also apply if you’re including your JavaScript code with {@link TemplatesService::includeJs()}.

BaseElementFieldType::getSettingsHtml()

View source (opens new window)

Returns

string (opens new window), null (opens new window)

Signature

public string, null getSettingsHtml ( )

getTableAttributeHtml()

IPreviewableFieldType::getTableAttributeHtml()

View source (opens new window)

Arguments

• $value (mixed)

Returns

string (opens new window)

Signature

public string getTableAttributeHtml ( $value )

prepSettings()

Preps the settings before they’re saved to the database.

ISavableComponentType::prepSettings()

View source (opens new window)

Arguments

• $settings (array (opens new window)) – The settings, as they exist in the POST data.

Returns

array (opens new window) – The prepped settings, which will be stored in the database.

Signature

public array prepSettings ( $settings )

prepValue()

Prepares the field’s value for use.

This method is called when the field’s value is first acessed from the element. For example, the first time entry.myFieldHandle is called from a template, or right before {@link getFieldHtml()} is called. Whatever this method returns is what entry.myFieldHandle will likewise return, and what getFieldHandle()’s $value argument will be set to.

IFieldType::prepValue()

IFieldType::prepValue()

View source (opens new window)

Arguments

• $value (mixed) – The field’s stored value.

Returns

mixed – The prepped value.

Signature

public mixed prepValue ( $value )

validate()

Validates the field’s value.

The $value passed into this method will be based on the value that {@link prepValueFromPost()} returned. It may have gone through additional modification when it was set on the {@link ContentModel} as well, depending on the attribute type {@link defineContentAttribute()} returns.

Some validation may already occur for this field without any help from this method. For example, if the field is required by the field layout, but doesn’t have any value, the {@link ContentModel} will take care of that. Also, if {@link defineContentAttribute()} defines any validation rules (e.g. min or max for Number attributes), those will also be applied automatically. So this method should only be used for custom validation rules that aren’t already provided for free.

IFieldType::validate()

IFieldType::validate()

View source (opens new window)

Arguments

• $value (mixed) – The field’s value.

Returns

true (opens new window), string (opens new window), array (opens new window) – true if everything checks out; otherwise a string for a single validation error, or an array of strings if there are multiple validation errors.

Signature

public true, string, array validate ( $value )
