In a sense I want to get:</p> <pre><code>First question? Answer1 Answer2 Second question? </code></pre> <p>But I'm getting</p> <pre><code>First question? Answer1 Answer2 Second question? Answer1 Answer2 </code></pre> <p>Second question need not to have Answer1 and Answer2(same with First question answers but I have two answer in mysql).</p> <p>And my foreach loops.. How need i to change my loops?</p> <pre><code>foreach($questions-&gt;getQuestion($_GET["category"]) as $data) // Questions { echo $data["question"] . "&lt;br/&gt;"; foreach($questions-&gt;getAnswer($data["id"]) as $answers) // Answers { echo $answers["answer"] . "&lt;br/&gt;"; // This needn't print data to below of Second Question } } </code></pre> <p>Functions:</p> <pre><code>public function getQuestion( $cat ) { if(empty($cat)) { header("location:index.php"); } $this-&gt;sql = "SELECT * FROM questions WHERE category='" . $cat . "'"; $data = parent::getData(); return $data; } public function getAnswer( $question ) { $this-&gt;sql = "SELECT * FROM answers WHERE questions='" . $question . "'"; $data = parent::getData(); return $data; } </code></pre> <p>Datas:</p> <pre><code> Array ( [0] =&gt; Array ( [id] =&gt; 1 [soru] =&gt; First Question [kategori] =&gt; 1 ) [1] =&gt; Array ( [id] =&gt; 2 [soru] =&gt; Second Question [kategori] =&gt; 1 ) ) Array ( [0] =&gt; Array ( [id] =&gt; 1 [soru] =&gt; First Question [kategori] =&gt; 1 ) [1] =&gt; Array ( [id] =&gt; 2 [soru] =&gt; Second Question [kategori] =&gt; 1 ) [2] =&gt; Array ( [id] =&gt; 1 [cevap] =&gt; Answer1 [sorular] =&gt; 1 ) [3] =&gt; Array ( [id] =&gt; 2 [cevap] =&gt; Answer2 [sorular] =&gt; 1 ) [4] =&gt; Array ( [id] =&gt; 1 [cevap] =&gt; Answer1 [sorular] =&gt; 1 ) [5] =&gt; Array ( [id] =&gt; 2 [cevap] =&gt; Answer2 [sorular] =&gt; 1 ) ) </code></pre> <p><em>note: these datas are only example.

    2. COYour example code looks fine.. if there are no answers to a question, they wouldn't display. What issue are you having? Are you asking people to write the getQuestion and getAnswer method?

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.
