我想用PHP函数创建HTML元素。在本节中,我有select
函数来创建select
标签。对于我想检查数组是否简单的值,我的函数创建简单的select
,否则为选项创建optgroup
。
我创建select
的方法:
$tag->select( 'myselect',
array(
'0'=>'please choose','1'=>'111','2'=>'222','3'=>'333'
) ,
'2',
array(
'class'=>'myClass','style'=>'width:10%;'
)
);
其他用途:
$tag->select( 'myselect',
array( 'one'=>
array('0'=>'please choose','1'=>'111','2'=>'222','3'=>'333'),
'two'=>
array('0'=>'please choose','1'=>'111','2'=>'222','3'=>'333')
) ,
'2',
array(
'class'=>'myClass','style'=>'width:10%;'
)
) ;
现在在下面的函数中,我想检查数组是否存在于数组中,函数必须是创建select group
;
public function select( $name, $values, $default='0', $attributs=[]){
$options = [];
$selected = '';
echo count($values);
if ( count($values) == 1){
foreach ($values as $value => $title) {
if ( $value === $default ) $selected="selected='selected'";
$options[] = "<option value = '$value' $selected>" . $title . '</option>'.PHP_EOL ;
$selected = '';
}
}
else{
foreach ($values as $key => $value) {
$options[] = "<optgroup label='$key'>";
foreach ($value as $selectValue => $title) {
$options[] = "<option value = '$selectValue'>" . $title . '</option>'.PHP_EOL ;
}
$options[] = "</optgroup>";
}
}
$selectTag = '<select ' . $this->setAttribute($attributs) . '>'.PHP_EOL;
return $selectTag . implode($options, ' ') . '</select>';
}
此函数不正确。如何解决这个问题?谢谢
试试这个(希望能帮助你)
public function select( $name, $values, $default='0', $attributs=[]){
$options = [];
$selected = '';
echo count($values);
foreach ($values as $key => $value) {
if (!is_array($value)) {
if ( $key === $default ) $selected="selected='selected'";
$options[] = "<option value = '$key' $selected>" . $value . '</option>'.PHP_EOL ;
$selected = '';
}
else {
$options[] = "<optgroup label='$key'>";
foreach ($value as $selectValue => $title) {
$options[] = "<option value = '$selectValue'>" . $title . '</option>'.PHP_EOL ;
}
$options[] = "</optgroup>";
}
}
$selectTag = '<select ' . $this->setAttribute($attributs) . '>'.PHP_EOL;
return $selectTag . implode($options, ' ') . '</select>';
}
