    <p>I am having some difficulty with my PHP/MySQL search. It worked great a year ago, but for some reason it has just stopped working. I have tried searching and cannot figure it out. I have it echo my query but it never adds in the WHERE clause. Any help is much appreciated.</p> <p>Form Code:</p> <pre><code>&lt;form name="search" method="post"&gt; &lt;p&gt;&lt;b&gt;Name of Property:&lt;/b&gt; &lt;input type="text" id="NameSrch" name="NameSrch" /&gt; (optional)&lt;/p&gt; &lt;p&gt;&lt;b&gt;City Your Looking to Stay In:&lt;/b&gt; &lt;input type="text" id="CitySrch" name="CitySrch" /&gt; (optional)&lt;/p&gt; &lt;p&gt;&lt;b&gt;Listing ID Number:&lt;/b&gt; &lt;input type="text" id="RentalIDSrch" name="RentalIDSrch" /&gt; (optional)&lt;/p&gt; &lt;p&gt;&lt;b&gt;Number of Bedrooms:&lt;/b&gt; &lt;input type="text" id="BedroomSrch" name="BedroomSrch" /&gt; (optional)&lt;/p&gt; &lt;p&gt;&lt;b&gt;Number of Bathrooms:&lt;/b&gt; &lt;input type="text" id="BathroomSrch" name="BathroomSrch" /&gt; (optional)&lt;/p&gt; &lt;p&gt;&lt;b&gt;Maximum Occupancy:&lt;/b&gt; &lt;input type="text" id="SleepsSrch" name="SleepsSrch" /&gt; (optional)&lt;/p&gt; &lt;input type="hidden" name="method" value="exSearch"&gt; &lt;p&gt;&lt;input type="submit" value="Search" /&gt;&lt;/p&gt; &lt;/form&gt; </code></pre> <p>PHP Code:</p> <pre><code>&lt;? $method = $_POST['method']; if($method == 'exSearch') { // Start Results Display $con = mysql_connect($dbhost, $dbuser, $dbpass) or die ('Error connecting to mysql: ' . mysql_error()); mysql_select_db($dbname); $query_string = 'SELECT * FROM TABLE '; $location_result_string = ""; $location_count = 0; if ($NameSrch) { if ($location_count &gt; 0) { $location_result_string = $location_result_string .

    1. COHow are the variables such as `$NameSrch, $CitySrch` set? Are they set at all or are you expecting them to be set through the POST? Because that doesn't work. You can access posted content through $_POST['fieldName']. Also, access variables inside a string like: 'blablabla '.$sName.' extra'; or if you use double quotes you can do it like "blablabla {$sName} extra".

    2. COThat is probably the problem. If you have the settings `REGISTER_GLOBALS=ON` this code can work but with `REGISTER_GLOBALS=OFF` (as it should be), you have to access the variables via `$_POST`

    3. COIf variables like `$NameSrch` are straightly taken from the user’s input, you’re script is probably vulnerable to SQL injection.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
