在您的插件目录中修改modules/select.php wpcf7_select_shortcode_handler 函数:
function wpcf7_select_shortcode_handler( $tag ) {
$tag = new WPCF7_Shortcode( $tag );
if ( empty( $tag->name ) )
return '';
$validation_error = wpcf7_get_validation_error( $tag->name );
$class = wpcf7_form_controls_class( $tag->type );
if ( $validation_error )
$class .= ' wpcf7-not-valid';
$atts = array();
$atts['class'] = $tag->get_class_option( $class );
$atts['id'] = $tag->get_option( 'id', 'id', true );
$atts['tabindex'] = $tag->get_option( 'tabindex', 'int', true );
if ( $tag->is_required() )
$atts['aria-required'] = 'true';
$atts['aria-invalid'] = $validation_error ? 'true' : 'false';
$defaults = array();
if ( $matches = $tag->get_first_match_option( '/^default:([0-9_]+)$/' ) )
$defaults = explode( '_', $matches[1] );
$multiple = $tag->has_option( 'multiple' );
$include_blank = $tag->has_option( 'include_blank' );
$first_as_label = $tag->has_option( 'first_as_label' );
$name = $tag->name;
$values = $tag->values;
$labels = $tag->labels;
$empty_select = empty( $values );
if ( $empty_select || $include_blank ) {
array_unshift( $labels, '---' );
array_unshift( $values, '' );
} elseif ( $first_as_label ) {
$values[0] = '';
}
$html = '';
$posted = wpcf7_is_posted();
foreach ( $values as $key => $value ) {
$selected = false;
// changed here
if (! ( $attributes = json_decode($value, true) ) ) {
$attributes = array(
'value' => $value
);
} else {
$value = (isset($attributes['value'])) ? $attributes['value'] : null;
}
if ( $posted && ! empty( $_POST[$name] ) ) {
if ( $multiple && in_array( esc_sql( $value ), (array) $_POST[$name] ) )
$selected = true;
if ( ! $multiple && $_POST[$name] == esc_sql( $value ) )
$selected = true;
} else {
if ( ! $empty_select && in_array( $key + 1, (array) $defaults ) )
$selected = true;
}
// changed here
$item_atts = array('selected' => $selected ? 'selected' : '' );
$item_atts = array_merge($attributes, $item_atts);
$item_atts = wpcf7_format_atts( $item_atts );
$label = isset( $labels[$key] ) ? $labels[$key] : $value;
$html .= sprintf( '<option %1$s>%2$s</option>',
$item_atts, esc_html( $label ) );
}
if ( $multiple )
$atts['multiple'] = 'multiple';
$atts['name'] = $tag->name . ( $multiple ? '[]' : '' );
$atts = wpcf7_format_atts( $atts );
$html = sprintf(
'<span class="wpcf7-form-control-wrap %1$s"><select %2$s>%3$s</select>%4$s</span>',
$tag->name, $atts, $html, $validation_error );
return $html;
}
现在您可以像以前一样调用插件,或者发送json的值(所有键都呈现为属性),即:
[select* select-profissao id:cd-dropdown class:cd-select '{"value":"Professional","class":"mytestclass"}' '{"value":"Nurse","more-attr":"Nurse Attribute"}']
很遗憾,我无法对此进行测试(未安装 wordpress)。
