    <p>In index.php I have a form and in the form a text field: </p> <pre><code>&lt;form name="UserSearch" action="petSearch.php" method="GET"&gt; &lt;input type="text" name="petWish" value="" /&gt; &lt;/form&gt; </code></pre> <p>where the user enters what pets they want into the text box (seperated by commas) e.g dog, cat, fish, snake</p> <p>In petSearch.php, I use the following function to create a legal SQL string that can be used in a SQL statement:</p> <pre><code>&lt;?php $userPetWish = mysqli_real_escape_string($link, $_GET["petWish"]); ?&gt; </code></pre> <p>I then create the SQL statement and query the MySQL database:</p> <pre><code>&lt;?php $query="SELECT petType, name, age FROM pets WHERE petType LIKE '%".$userPetWish."%'"; $result = mysqli_query($link, $query); if($result) { while($row = mysqli_fetch_array($result)) { echo "From the pets you entered we have" . $row[petType] . "," . $row[name] . "," . $row[age]; } } else { echo "Sorry we do not have any of your chosen pets in store"; } ?&gt; </code></pre> <p>So my question is:</p> <p>1) In order to search for each individual pet against the database, is it possible to <strong>'split'</strong> the pets which the user entered by commas and then query the Pet table in the database using the "LIKE" function? If so, can you tell me how to structure this?</p> <p>2) If after doing the search against the database there is a dog, cat and fish in store, but no snake. How do i get it to display this, to show the petType, name and age they have of the three pets, but not the snake? (I'm not sure if the way I structured this in the while loop is correct)</p>

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.
