    <p>I am using PHPExcel class and i am loading template speadsheets and then modifying data and so forth.</p> <p>Depending on what i pass my script dynamically, certain images in the template should be remove and certain graphs(charts) should be removed.</p> <p>I have used the <code>getChartCollection()</code> and the <code>getDrawingCollection()</code> to get everything but i havent figured out a way to modify the collections so that i can remove charts, and/or images from a loaded template.</p> <p>Thanks for any help. Jason K.</p> <p>UPDATE - Thanks to info from Mark Baker below. I wrote the following code that needs to be added to worksheet class until 1.7.9 is released. My code is below.</p> <pre><code>/** * Remove drawing from collection * * @return PHPExcel_Worksheet_BaseDrawing[] */ public function removeImageByIDs($IDs) { if(!is_array($IDs)) $IDs = array($IDs); $drawing_collection = $this-&gt;_drawingCollection; $drawing_collection_copy = $drawing_collection-&gt;getArrayCopy(); foreach($IDs as $ID){ unset($drawing_collection_copy[$ID]); } $drawing_collection_copy = array_values($drawing_collection_copy); $drawing_collection-&gt;exchangeArray($drawing_collection_copy); $this-&gt;_drawingCollection = $drawing_collection; unset($drawing_collection_copy); unset($drawing_collection); return $this-&gt;_drawingCollection; } /** * Remove chart from collection * * @return PHPExcel_Worksheet_BaseDrawing[] */ public function removeChartByIDs($IDs) { if(!is_array($IDs)) $IDs = array($IDs); $chart_collection = $this-&gt;_chartCollection; $chart_collection_copy = $chart_collection-&gt;getArrayCopy(); foreach($IDs as $ID){ unset($chart_collection_copy[$ID]); } $chart_collection_copy = array_values($chart_collection_copy); $chart_collection-&gt;exchangeArray($chart_collection_copy); $this-&gt;_chartCollection = $chart_collection; unset($chart_collection_copy); unset($chart_collection); return $this-&gt;_chartCollection; } </code></pre> <p>Enjoy.

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.
