Question

我正在使用php创建一个网页，在这个页面我必须使用php搜索起始地点到交付地点的详细信息这可能吗？

我的代码如下：

的index.php

<form id="contactForm" action="index.php" novalidate>
   <label>Starting Place</label>
   <input type="text" name="starting_place" placeholder="Enter Starting Place">
   <label>Starting Place</label>
   <input type="text" name="delivery_place" placeholder="Enter Starting Place">
   <input type="submit" name="search" value="search">
</form>
<?php
include 'db.php';
if(isset($_POST['search']))
{
    $sql = mysql_query("select * from place where "); // this is my question

    while($row = mysql_fetch_array($sql))
    {
        echo $row['starting_place'];
        echo $row['delivery_place'];
    }
}
?>

Answer 1

我认为你的查询不好

$sql =mysql_query("select * from place where ");

也许你会这样做

$search = $_POST['search'];
$sql =mysql_query("select * from `place` where `starting_place` = '$search' ");

完整的PHP代码

include 'db.php';
   if(isset($_POST['search']))
   {
       $search = $_POST['search'];
       $sql =mysql_query("select * from `place` where `starting_place` = '$search' ");
       while($row = mysql_fetch_array($sql))
       {
           echo $row['starting_place'];
           echo $row['delivery_place'];
       }
   }

Answer 2

mysql_*已被弃用，请使用mysqli _ * or pdo`而不是

检查此查询：

$start = $_POST['starting_place'];
$end = $_POST['delivery_place'];
$sql = mysql_query("select * from place where starting_place = $start and ending_place = $end ");

Answer 3

你的问题不是很清楚。我假设你只有一个输入字段：

<form id="contactForm" action="index.php" novalidate>
    <label>Starting Place</label>
    <input type="text" name="starting_place" placeholder="Enter Starting Place">
    <input type="submit" name="search" value="search">
</form>

然后，您的PHP代码应如下所示：

$starting_place = $_POST['starting_place']; //name of your input box

if (isset($starting_place)) {
    $sql = mysql_query("select * from place where place='" . $starting_place . "'"); 
    while($row = mysql_fetch_array($sql)) {
        echo $row['starting_place'];
        echo $row['delivery_place'];
    }
}
