我要加 title="icons/icon_cart.gif"对于使用 View 呈现的选择列表中的以下每个选项。
在尝试并阅读了许多文章后,我似乎找不到将此 html 添加到我的表单中的方法。
下面是我的代码。
function customchatter_form_alter(&$form, &$form_state, $form_id) {
$form["tid"]["#options"][1]=t("nooo chatter");
// this works to change the label of the option but how do I add title="icons/icon-
cart.gif" ?
}
我的html代码:
<select id="edit-tid" name="tid" class="form-select">
<option value="All">- Any -</option>
<option value="1">nooo chatter</option>
<option value="2">Complaints Complaints</option>
<option value="3">Gear & Gadgets</option>
</select>
干杯,

更新
我尝试按照克莱夫的建议更新代码,但值仍然不正确。下面是我的故事。
所以下面是我能够实现的 html 输出,但标题似乎总是数字 1。
<select id="edit-select" class="form-select" name="select">
<option value="1" title="1">One</option>
<option value="2" title="1">Two</option>
</select>
如您所见,标题在那里,但值是错误的。下面是我的表格和我写的函数。
我的表格:
$form['select'] = array(
'#type' => 'select',
'#options' => array(1 => 'One', 2 => 'Two'),
'#title' => array(1 => 'One', 2 => 'Two')
// I tried many combinations but nothing seems to work.
);
我的主题功能。
function kt_vusers_select($variables) {
$element = $variables['element'];
element_set_attributes($element, array('id', 'name', 'size'));
_form_set_class($element, array('form-select'));
return '<select' . drupal_attributes($element['#attributes']) . '>' .
kt_vusers_form_select_options($element) . '</select>';
}
function kt_vusers_form_select_options($element, $choices = NULL) {
if (!isset($choices)) {
$choices = $element['#options'];
}
// array_key_exists() accommodates the rare event where $element['#value'] is NULL.
// isset() fails in this situation.
$value_valid = isset($element['#value']) || array_key_exists('#value', $element);
// @vishal so there I have declared the variable to accept the values.
$vtitle = isset($element['#title']) || array_key_exists('#title', $element);
$value_is_array = $value_valid && is_array($element['#value']);
$options = '';
foreach ($choices as $key => $choice) {
if (is_array($choice)) {
$options .= '<optgroup label="' . $key . '">';
$options .= form_select_options($element, $choice);
$options .= '</optgroup>';
}
elseif (is_object($choice)) {
$options .= form_select_options($element, $choice->option);
}
else {
$key = (string) $key;
if ($value_valid && (!$value_is_array && (string) $element['#value'] === $key ||
($value_is_array && in_array($key, $element['#value'])))) {
$selected = ' selected="selected"';
}
else {
$selected = '';
}
// @vishal this is where the variable is being used.
$options .= '<option title="'.$vtitle.'" value="' . check_plain($key) . '"' . $selected .
'>' . check_plain($choice) . '</option>';
}
}
return $options;
}
下面是最后一个主题功能的正确代码
function kt_vusers_form_select_options($element, $choices = NULL, $vtitles=NULL) {
// Build up your own version of form_select_options here
// that takes into account your extra attribute needs.
// This will probably involve inspecting your custom FAPI property,
// which we'll call #extra_option_attributes
if (!isset($choices)) {
$choices = $element['#options'];
$vtitles = array();
$vtitles = $element['#title'];
}
// array_key_exists() accommodates the rare event where $element['#value'] is NULL.
// isset() fails in this situation.
$value_valid = isset($element['#value']) || array_key_exists('#value', $element);
$value_is_array = $value_valid && is_array($element['#value']);
$options = '';
// print_r($vtitles);
尽管
(
(list($key, $choice) = each($choices))
&& (list($keytwo, $vtitle) = each($vtitles))
)
{
//printf("%s => %s, %s => %s\n", $key1, $value1, $key2, $value2);
if (is_array($choice)) {
$options .= '<optgroup label="' . $key . '">';
$options .= kt_vusers_form_select_options($element, $choice);
$i++;
// $options .= form_select_options($element, $vtitle);
$options .= '</optgroup>';
} // end if if is_array
elseif(is_object($choice)) {
$options .= form_select_options($element, $choice->option);
} // end of else if
else {
$key = (string) $key;
if ($value_valid && (!$value_is_array && (string) $element['#value'] === $key ||
($value_is_array && in_array($key, $element['#value'])))) {
$selected = ' selected="selected"';
}
else {
$selected = '';
}
// $options .= '<option title="'.$vtitle.'" value="' . check_plain($key) . '"' .
$selected . '>' . check_plain($choice) . '</option>';
}
$options .= '<option value="'. check_plain($key) .'" title="' . $vtitle . '"' . $selected
.'>'. check_plain($choice) .'</option>';
} // end of choice
return $options;
} // end of function
最佳答案
恐怕你得挖得很深才能做到这一点,#options
数组在 form_select_options()
中被展平它目前不包括任何添加属性的方式。这是代码:
$options .= '<option value="' . check_plain($key) . '"' . $selected . '>' . check_plain($choice) . '</option>';
如您所见,那里根本没有属性的范围。您将能够覆盖它,但这将涉及实现您自己的
theme_select()
版本。和您自己的 FAPI 属性(property)。我没有时间充实整个事情,但在你的主题文件中你会做这样的事情:
function MYTHEME_select($variables) {
$element = $variables['element'];
element_set_attributes($element, array('id', 'name', 'size'));
_form_set_class($element, array('form-select'));
return '<select' . drupal_attributes($element['#attributes']) . '>' . MYTHEME_form_select_options($element) . '</select>';
}
function MYTHEME_form_select_options($element) {
// Build up your own version of form_select_options here
// that takes into account your extra attribute needs.
// This will probably involve inspecting your custom FAPI property,
// which we'll call #extra_option_attributes
}
引用 form_select_options用于施工
MYTHEME_form_select_options
您在表单中的代码将类似于:
$form['select'] = array(
'#type' => 'select',
'#options' => array(1 => 'One', 2 => 'Two'),
'#extra_option_attributes' => array(
1 => array('title' => 'Test title'), // Attributes for option with key "1",
2 => array('title' => 'Test title'), // Attributes for option with key "2",
)
);
在
MYTHEME_form_select_options()
然后你可以检查元素的 #extra_option_attributes
键(如果存在)以查看您是否需要在您创建的 HTML 中物理添加更多属性。希望有帮助,我知道这似乎是一种疯狂冗长的方式来做你需要做的事情,但据我所知,这是唯一的方法。
