Body
<p>This problem can be easily solved by using an <strong>.htaccess</strong> rewrite. </p> <p>Demo:</p> <p>A. Create a directory named "iframeContent/" on SERVER 1.</p> <p>B. Place in that directory a file named index.php containing:</p> <blockquote> <pre><code><html> <head></head> <body> <script type="text/javascript"> parent.check(); </script> </body> </html> </code></pre> </blockquote> <p>This is the content of the iFrame. It will call a function in a parent.</p> <p>C. Create a directory named "iframeTesting_without-htaccess/" on SERVER 2.</p> <p>D. Place in that directory a file named index.php containing: </p> <blockquote> <pre><code><html> <head></head> <body> <script type="text/javascript"> function check() { alert("hello"); } </script> <iframe id="sidebnrId" name="sidebnr" src="PATH-ON-SERVER-1/iframeContent/" frameborder="0" height="500px" width="600px" scrolling="no"></iframe> </script> </body> </html> </code></pre> </blockquote> <p>This is simply the content of the parent windows. Just note that the iFrame content is located on another server (because on SERVER 1).</p> <p>E. Access "PATH-ON-SERVER-2/iframeTesting_without-htaccess/" with a web-browser -> nothing happens: the iframe does not have access to the function of its parent.</p> <p><strong>HERE IS HOW YOU CAN SOLVE THE PROBLEM</strong></p> <p>F. Create another directory named "iframeTesting_with-htaccess/" on SERVER 2.</p> <p>G. Place in that directory a file named index.php containing: </p> <blockquote> <pre><code><html> <head></head> <body> <script type="text/javascript"> function check() { alert("hello"); } </script> <iframe id="sidebnrId" name="sidebnr" src="content-iframe/" frameborder="0" height="500px" width="600px" scrolling="no"></iframe> </script> </body> </html> </code></pre> </blockquote> <p>This time the iFrame does not point anymore directly to the content on SERVER 1 but to an intermediate fictive directory "content-iframe/" located on the same server (SERVER 2).</p> <p>H. Place in that directory a .htaccess file containing: </p> <blockquote> <pre><code>Options +FollowSymLinks RewriteEngine On RewriteBase / RewriteRule ^content-iframe/$ PATH-ON-SERVER-1/iframeContent/ [R,NC,P] </code></pre> </blockquote> <p>The role of that file is to redirect any access to the fictive directory to the content on the SERVER 1.</p> <p>I. Try again, access "PATH-ON-SERVER-2/iframeTesting_with-htaccess/" with a web-browser. This time it will work. I hope it helped :-)</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.
