[英]PHP: Input MySQL query
Hey guys I am a little confused, I have a listing page that displays all of my rows in my SQL table. 大家好,我有点困惑,我有一个列表页面,显示我的SQL表中的所有行。
An example of what I am developing can be seen here: http://www.drivencarsales.co.uk/used-cars.php 在此可以看到我正在开发的示例: http : //www.drivencarsales.co.uk/used-cars.php
So as you can see I have developed a listing page that fetches all of the table rows, each row is equivalent to one vehicle. 因此,正如您所看到的,我开发了一个列表页面,该页面可获取所有表行,每一行等效于一种车辆。
I now want to let users filter the results using the form to the left, I was going to use AJAX originally however I feel as if it would take way to long to learn how to develop it that way. 现在,我想让用户使用左侧的表单过滤结果,我本来打算使用AJAX,但是我觉得学习这种方式开发似乎需要很长时间。
Here is the code setup I am using to achieve the example I have shown: 这是我用来实现所示示例的代码设置:
<?php
include('database.php');
try {
$results = $db->query("SELECT Make, Model, Colour, FuelType, Year, Mileage, Bodytype, Doors, Variant, EngineSize, Price, Transmission, PictureRefs, ServiceHistory, PreviousOwners, Options, FourWheelDrive FROM import ORDER BY Make ASC");
} catch (Exception $e) {
echo "Error.";
exit;
}
try {
$filterres = $db->query("SELECT DISTINCT Make FROM import ORDER BY Make ASC");
} catch (Exception $e) {
echo "Error.";
exit;
}
?>
As you can see the first block of code has two SQL selectors, the $results is used to fetch the whole table and list all vehicles. 如您所见,第一个代码块具有两个SQL选择器,$ results用于获取整个表并列出所有车辆。
The second block is used to display the 'Make' column for the form. 第二个块用于显示表单的“制作”列。
This block of code is the actual form: 此代码块是实际形式:
<form>
<select class="form-control select-box" name="">
<option value="make-any">Make (Any)</option>
<?php while($make = $filterres->fetch(PDO::FETCH_ASSOC))
{
echo '
<option value="">'.$make["Make"].'</option>
';
} ?>
</select>
<button href="#" class="btn btn-block car-search-button btn-lg btn-success"><span class="glyphicon car-search-g glyphicon-search"></span> Search cars
</button>
</form>
As you can see this block is using a while loop to display all of the 'Make's' in the 'Make' column and uses a DISTINCT clause so that it doesn't show identical options. 如您所见,此块正在使用while循环在“ Make”列中显示所有“ Make”,并使用DISTINCT子句,以便不显示相同的选项。
Here is the block that lists the results to the page: 这是将结果列出到页面的块:
<?php while($row = $results->fetch(PDO::FETCH_ASSOC))
{
echo '
<div class="listing-container">
<a href="carpage.php"><h3 class="model-listing-title clearfix">'.$row["Make"].' '.$row["Model"].' '.$row["Variant"].'</h3></a>
<h3 class="price-listing">£'.number_format($row['Price']).'</h3>
</div>
<div class="listing-container-spec">
<img src="'.(explode(',', $row["PictureRefs"])[0]).'" class="stock-img-finder"/>
<div class="ul-listing-container">
<ul class="overwrite-btstrp-ul">
<li class="diesel-svg list-svg">'.$row["FuelType"].'</li>
<li class="saloon-svg list-svg">'.$row["Bodytype"].'</li>
<li class="gear-svg list-svg">'.$row["Transmission"].'</li>
<li class="color-svg list-svg">'.$row["Colour"].'</li>
</ul>
</div>
<ul class="overwrite-btstrp-ul other-specs-ul h4-style">
<li>Mileage: '.number_format($row["Mileage"]).'</li>
<li>Engine size: '.$row["EngineSize"].'cc</li>
</ul>
<button href="#" class="btn h4-style checked-btn hover-listing-btn"><span class="glyphicon glyphicon-ok"></span> History checked
</button>
<button href="#" class="btn h4-style more-details-btn hover-listing-btn tst-mre-btn"><span class="glyphicon glyphicon-list"></span> More details
</button>
<button href="#" class="btn h4-style test-drive-btn hover-listing-btn tst-mre-btn"><span class="test-drive-glyph"></span> Test drive
</button>
<h4 class="h4-style listing-photos-count"><span class="glyphicon glyphicon-camera"></span> 5 More photos</h4>
</div>
';
} ?>
So down to my question... How can I filter these results displayed in the listing block using the select element, when a user selects a 'Make' from the select element I want them to be able to submit the form and return all rows in the SQL table containing the same 'Make' string and hide other rows that are false. 所以请问我的问题...当用户从select元素中选择“制作”时,如何使用select元素过滤显示在列表框中的结果,我希望他们能够提交表单并返回所有行在包含相同“ Make”字符串的SQL表中,并隐藏其他错误的行。
Any ideas how I can achieve this or any easier ways? 有什么想法可以实现这一目标或更简单的方法吗?
Thanks 谢谢
My best guess is for you to use JS to submit the form again, when select-option is selected, with a parameter stating the model. 我最好的猜测是,当选择了select-option时,使用JS再次提交表单,并带有说明模型的参数。
Then in your PHP file, you should look for that parameter and edit the query-string accordingly. 然后,在您的PHP文件中,您应该寻找该参数并相应地编辑查询字符串。
see this answer on how to submit a form when option is selected. 有关选择选项时如何提交表单的信息,请参见此答案 。
