Respected Sir, I want to add a sort by key for all the columns in a table of a database.Currently there is a sort by key only for the primary key.I thought i would use the existing code for sorting primary key. That's why i used the inspect element function for the sort by key option in phpmyadmin panel and this is what i got Sort by key: <option value="SELECT * FROM `accounts` ORDER BY `s.no.` ASC">PRIMARY (Ascending)</option><option value="SELECT * FROM `accounts` ORDER BY `s.no.` DESC">PRIMARY (Descending)</option><option value="SELECT * FROM `accounts`" selected="selected">None</option> But the above code cant be found anywhere in the source code i downloaded from github .Is it function generated? Also i found that php is not the only thing phpmyadmin is made of there is javascript and loads of other stuff ..please tell me what are the languages i need to learn to completely understand phpmyadmin code . which are the books i should refer for that ?? Is there any place where phpmyadmin code is completely explained for beginners or are we on our own?? -- yours sincerely, Tapesh Mandal On 1/17/14, Tapesh Mandal &lt;tapesh.mandal(a)gmail.com&gt; wrote: -- Tapesh Mandal Flat No. S-1 Wastusakha Sahaniwas 185/3, J.B.Thakkar Marg P.O.
