我有一个带有一个输入字段但有两个按钮的表单。我们的想法是使用代码签入或签出。进程来到php文件,它只以一个空白页结束。怎么了?
修改 我将“btn_in”更改为“inputAnst_nr”现在它可以登录。但是,我如何按下按钮?
HTML
<form class="form-inline well" id="usr_stamp" name="usr_stamp" method="post" action="php/usr_time_reg.php">
<div class="control-group">
<input id="inputAnst_nr" name="inputAnst_nr" class="form-control input-lg" placeholder="Ange Anst. nr" type="tel">
<button id="btn_in" name="btn_in" class="btn btn-lg btn-info primary col-sm-offset-1" type="submit">In</button>
<button id="btn_out" name="btn_out" class="btn btn-lg btn-danger primary col-sm-offset-1" type="submit">Ut</button>
</div>
</form>
JS
$(document).ready( function () {
$("#btn_in").on('click', function() {
$("#usr_stamp").attr("action", "php/usr_time_reg.php");
});
$("#btn_out").on('click', function() {
$("#usr_stamp").attr("action", "php/usr_time_reg.php");
});
});
PHP
//Check if POST is empty
if(!empty($_POST)){
//Check if POST is "inputAnst_nr"
if(!empty($_POST['inputAnst_nr'])){
//Put POST_btn_in in variable
$posted_anst_nr = $_POST['inputAnst_nr'];

您可以为两个按钮使用相同的名称属性值,只需确保指定适当的值即可。例如:
<?php
if(isset($_POST['btn_in_out'])) {
$status = $_POST['btn_in_out']; // In or Out depending on which one you clicked
echo $status;
}
?>
<form class="form-inline well" id="usr_stamp" name="usr_stamp" method="post">
<div class="control-group">
<input id="inputAnst_nr" name="inputAnst_nr" class="form-control input-lg" placeholder="Ange Anst. nr" type="tel">
<button id="btn_in" name="btn_in_out" type="submit" value="In">In</button>
<button id="btn_out" name="btn_in_out" type="submit" value="Out">Ut</button>
</div>
</form>
