php让checkbox复选框初始选中,很常用的功能,备忘下:
代码如下:
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> <?php $arr=array(0=>array(‘id‘=>100,‘title‘=>‘京东‘),1=>array(‘id‘=>200,‘title‘=>‘天猫‘),2=>array(‘id‘=>300,‘title‘=>‘苏宁‘)); $arrId=array(100,300); if( isset($_POST[‘mall‘]) ){ echo ‘<pre />‘; print_r($_POST[‘mall‘]); exit(); } ?> <form action="" method="post"> <?php foreach ($arr as $key=>$value){?> <?php if( in_array($value[‘id‘],$arrId) ){?> <input type="checkbox" name="mall[]" value="<?php echo $value[‘id‘]?>" checked><?php echo $value[‘title‘]?> <?php }else{?> <input type="checkbox" name="mall[]" value="<?php echo $value[‘id‘]?>"><?php echo $value[‘title‘]?> <?php }?> <?php }?> <input type="submit" value="提交" /> </form>
