Question

I need a way to insert images into a PostgreSQL database without using forms. I have a folder that contains a set of images named say aa.jpg, bb.jpg …. zz.jpg. I also have a table that contains the names aa,bb…zz as individual records.

Now my question is how do I insert these images into the DB without manually using forms. There are loads of Yii tutorials to do the manual insertion, but none explaining how to do it programmatically.

Basically I need a way to use lo_import function in Yii. The thing is, image is a column in the table whose type is OID and my insertion code in Yii is as follows

update('table_name', array(
                'image' => "lo_import('$image_path')",
                    ), 'column=:name', array(':name' => $name));

on executing this, it gives me the following error

CDbCommand failed to execute the SQL statement: SQLSTATE[22P02]: Invalid text representation: 7 ERROR: invalid input syntax for type oid:

Solution: Ok, so following @Uday’s answer, I just used the function in Yii to execute sql statements directly.

Yii::app()->db->createCommand($Update_sql_command)->query();

I am all ears if there is a better way to do this.
Thanks!

Do you really need Yii for that? write a function to iterate through all images use get_file_contents() to get contents and store it to mysql.

$imgContents = get_file_contents('file.Name') ;
$sql = 'insert into table_name (blob_column) values("'. $imgContents.'")';
