我创建了一个HTML表单,其中包含一个下拉列表 postgresql数据库,我希望在表单中有一些字段 从中选择项目时自动从数据库填充 下拉菜单。我在表格上还有其他一些字段 需要在按下提交按钮之前填写用户 将整个数据推回数据库。
目前我的脚本无法连接到数据库或填充 表格上的下拉列表,也无法自动填充 其他指定的表单字段(这是项目的属性) 在下拉列表中也存储在数据库中)和第二个问题 即时通讯也是将数据输入输入字段后 点击提交。它在数据库中创建一条新记录而不是 填充数据库中的必需列。有人可以 看看我的剧本并帮助我。
以下是使用a创建数据输入表单的脚本 下拉

Php脚本将数据加载到表单字段并从中推送数据 数据库 - filename = check1.php

答案 0 :(得分:2)
我会通过使用Ajax和JQuery来做到这一点。您需要做三件事 - 在文档的head
中添加Ajax / JQuery代码,为Ajax创建要连接的php文件,然后添加onChange
,id
&amp; value
属性到字段。
在<head></head>
- <title></title>
-
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script>
<script type="text/javascript">
function check(){
var pipeno = $('#pipeno').val();
if(pipeno != "pipeno"){
jQuery.ajax({
type: "POST",
url: "check.php",
data: 'pipeno='+pipeno,
cache: false,
success: function(response){
var response_array = JSON.parse(response);
$('#wallthickness').val(response_array['wallthickness']);
$('#jointno').val(response_array['jointno']);
$('#measuredlength').val(response_array['measuredlength']);
$('#serialno').val(response_array['serialno']);}
});
}
else{
$('#wallthickness').val('');
$('#jointno').val('');
$('#measuredlength').val('');
$('#serialno').val('');}
}
</script>
然后使用代码 -
创建名为check.php
的文件
<?php
//Php Code to connect to postgresqldatabase
include ("connection.php");
// Code to pull data from the database and load onto the form
$pipeno = pg_escape_string($_POST['pipeno']);
$query = "SELECT * FROM fieldtally WHERE pipeno = $pipeno ";
$result = pg_query($db_handle,$query);
$row = pg_fetch_row($result))
$row_info = array('wallthickness'=>$row[1],'jointno'=>$row[2],'measuredlength'=>$row[3],'serialno'=>$row[4]);
$row_info = json_encode($row_info);
print_r($row_info);
?>
最后,添加id
&amp; value
属性到表单字段(不要更改文件,只需更新这些行)
Select Pipe No:<select name="pipeno" id="pipeno" onChange="check()"><option value="pipeno"> --Select-- </option>
... (keep your database connection / how you create your dropdown, etc here, just edit the option below)
echo "<option value=\"$pipeno\"> $pipeno</option>";
... (keep your database connection / how you create your dropdown, etc. here)
</select>
...
Input Joint No: <input type="text" name="jointno" id="jointno">
Input Wall Thickness: <input type="text" name="wallthickness" id="wallthickness">
Input measured Length: <input type="text" name="measuredlength" id="measuredlength">
Input Serial No: <input type="text" name="serialno" id="serialno">
更新10/19由于代码更改 -
我已在您的代码中放置编号的锚点,并且注释在最后。你可以在2个文件中完成所有操作,但是第二个文件check1.php
只能有1个数据库查询,否则你的ajax会有错误。

以下是问题 -
1 - 将所有<?php ?>
脚本移至页面顶部。这将:(1)清理代码,(2)能够同时处理所有数据库查询。
2 - 现在,在您从数据库获取下拉列表之前,您的更新fieldtally1
的查询已经完成。
3 - 修复第二个问题after entering data into the input fields and click submit. it creates a new record in the database instead of populating the required columns in the database
使用INSERT INTO ... VALUES ... ON DUPLICATE KEY UPDATE ...
。如果pipeno
已经在数据库中(因为它是Primary Key
),它将UPDATE
而不是INSERT
。
4 - 我建议保存您的error
或success
消息(#4a)并将其回显到您的HTML顶部(#4b)。
5a - 您已从硬编码pipeno
下拉列表更改为使用该功能的动态下拉列表。所以你错过了javascript - onChange=check();
5b - 现在您正在创建pipeno
&amp;动态onChange=check();
,您必须更改check()
函数以动态获取ID。
6 - $PHP_SELF
无效。我认为您正在尝试使用$_SERVER['PHP_SELF']
,但这很容易被黑,所以最好只使用action=""
。 [6.1,6.2,6.3]
7 - 当您<select><option>
使用相同的value=""
时,但是每个人在发布时都需要有所不同才能获得价值。此外,大多数</option>
拼写错误为</optio>
。 [7.1,7.2,7.3]
8 - 如果您在同一页面上有3个表单,则每个表单必须具有不同的名称,否则您将无法确定单击了哪个提交按钮。 [8.1,8.2,8.3]
9 - 您的前两个表单缺少结束标记 - </td></tr></table></form>
。 [9.1,9.2]
10 - 在你2&amp; 3个表单,您正在使用第一个表单中使用的id
。这是无效的,因为每个id
必须是唯一的。 [10.1,10.2]
11 - 第3个表单使用表单2中使用的id="wallthickness"
。请参阅上文有关id
唯一性的信息。
答案 1 :(得分:0)
如果要填充文本字段的数据是select选项的属性,我将使用jquery。拉出要使用的选定选项属性,然后可以使用jquery将其输出到文本框。它可以由选择菜单上的更改事件触发。例如..
$('#selectid').change(function() {
var opt = $('#selectid option:selected');
$('#text1id').val(opt.attr('attrfortext1'));
$('#text2id').val(opt.attr('attrfortext2'));
$('#text3id').val(opt.attr('attrfortext3'));
});
我认为使用Ajax访问另一个PHP文件来解析数据库并返回一个json编码数组,其中包含要填充文本字段的数据。根据您筛选的数据量,如果每个选项有多个属性,并且有100个选项,那么您的方法可能会很快变得难看。
