我想在用户完成2个输入时从db获取数据，这些是两个日期，1是开始日期，另一个是结束日期。当用户单击该按钮时，它应该在给定输入时从数据库中检索数据。但是当我点击我的按钮时，它什么也没发生。有人知道我的错误在哪里吗？这是我的两个文件。

这是按钮点击的代码：
<?php
//search.php
//require('neutest.php');
if(isset($_POST["from_date"], $_POST["to_date"]))
{
$conn = oci_connect('IPA_admin','*******','localhost/IPADB');
$query = oci_parse($conn,'SELECT * FROM STOPPOINT_NAMES WHERE DATUM BETWEEN '.$_POST["from_date"].' AND '.$_POST["to_date"].'');
oci_execute($query);
$output .='
<table class="table table-bordered">
<tr>
<th>STOPPOINT ID</th>
<th>STOPPOINT NAME</th>
<th>DATUM</th>
<th>DISTANCE</th>

';
if(oci_num_rows ($query) > 0)
{
while(($row = oci_fetch_array($query, OCI_BOTH)) != false)
{
$output .= '
<tr>
<td>'. $row["STOPPOINTID"] .'</td>

else

将表单添加到html，并将btn更改为提交到同一页面（如果搜索的php代码在同一页面中）。
HTML：
<from method="post" id="myForm">
<div class="input-daterange">
<div align="col-md-6">
<p>VON</p>
<input type="date" name="start_date" id="start_date" max="3000-12-31" min="1000-01-01" class="form-control">
</div>
<div align="col-md-6">
<p>BIS</p>
<input type="date" name="end_date" id="end_date" min="1000-01-01" max="3000-12-31" class="form-control">
</div>
</div>
</br>
<div align="center" class="col-md-3">
<input type="submit" name="filter" id="filter" value="Search" class="btn btn-info" />
</div>
</form>
JS：
$('#myForm').submit(function (event) {
event.preventDefault();
$.ajax({
url: "urlToPhpFile",
type: "POST",
dataType: 'json'
data: $(this).serialize(),
success: function(result){
}
}
});
});
