当选择区域时，PHP填充数据库中的数据 [英] PHP populate the data from database when District is selected
问题描述
请关注此信息检查我的以下信息
链接多个选择
我有这个代码，用户选择特定类别的医生，然后选择他想要查看的区域。之后，他需要点击车站（在选定的地区）
医生>>区>>车站
是代码
< html>
< body>
< form action =process.phpmethod =post>
< select name =cat>
<？php
$ sql =按照类别asc从医生顺序中选择不同类别;
$ query = mysql_query（$ sql）;
while（$ row = mysql_fetch_array（$ query））
{
echo< option value ='{$ row [Category]}'> {$ row [类别]}< / option>;
}
？>
< / select>
< select name =station>
<？php
$ sql_1 =选择不同的站从医生顺序由站asc;
$ query_1 = mysql_query（$ sql_1）;
while（$ row = mysql_fetch_array（$ query_1））
{
echo< option value =。$ row [Station]。& 。$ row [Station]。< / option>;
}
？>
< / select>
< input name =Ctype =submit/>
< / form>
< / body>
< / html>
Process.php
$ mySqlStm =SELECT Name FROM doctors WHERE Category ='$ myValue'and Station ='$ myStation';
$ result2 = mysql_query（$ mySqlStm）或die（Error：mysql_error（））;
if（mysql_num_rows（$ result2）== 0）{
echo（< br /> no records found）;
}
ELSE
{
echo< table border ='1'>;
// ECHO RECORDS FETCHED
while（$ row = mysql_fetch_array（$ result2））
{
echo< tr>;
// echo< td> 。 $ row ['Station']。 < / td>;
echo< td> 。 $ row ['Name']。 < / td> ;
// echo< td> 。 $ row ['Phone 1']。 < / td>;
// echo< td> 。 $ row ['Mobile']。 < / td>;
}
我想要车站类别选择并且当选择一类医生时，该区必须被自动填充。
我该如何做？我喜欢Javascript，因为我知道一点点。
此外，我有一个数据库中的所有数据，它看起来像这样
站|区|名称|资格等
Ajax + jQuery会在几行代码中为您完成。

please follow this post instead Check my following post please Chained multiple selects
I have this code where a user selects the particular category of doctor and then the District in which he wants to look it. After state he needs to click the station(in the selected district) Doctor >> District >> Station
Here is the code
<html>
<body>
<form action="process.php" method="post">
<select name="cat">
<?php
$sql="select distinct Category from doctors order by Category asc";
$query=mysql_query($sql);
while($row=mysql_fetch_array($query))
{
echo "<option value='{$row[Category]}'>{$row[Category]}</option>";
}
?>
</select>
<select name="station">
<?php
$sql_1="select distinct Station from doctors order by Station asc";
$query_1=mysql_query($sql_1);
while($row=mysql_fetch_array($query_1))
{
echo "<option value=".$row[Station].">".$row[Station]."</option>";
}
?>
</select>
<input name="C" type="submit" />
</form>
</body>
</html>
Process.php
$mySqlStm ="SELECT Name FROM doctors WHERE Category='$myValue' and Station='$myStation'";
$result2 = mysql_query($mySqlStm) or die("Error:mysql_error()");
if(mysql_num_rows($result2) == 0){
echo("<br/>no records found");
}
ELSE
{
echo "<table border='1'>";
//ECHO THE RECORDS FETCHED
while($row = mysql_fetch_array($result2))
{
echo "<tr>";
//echo "<td>" . $row['Station'] . "</td>";
echo "<td>" . $row['Name'] . "</td>" ;
//echo "<td>" . $row['Phone 1'] . "</td>";
//echo "<td>" . $row['Mobile'] . "</td>";
}
I want the station category to be auto filled when district is selected and When a category of doctor is selected, the district has to be auto filled.
How can I do it? I would prefer Javascript because I know a little bit about it. Also, i have all the data in one database it looks like this
Category | Station | District | Name | Qualification and so on
Ajax + jQuery will do that for you in a few lines of code.
