    <p>Hi I'm making a picture competition page (with different rules)</p> <p>I can't seem to wrap my head around this 'problem'</p> <p>The rule is: A user can vote for ONE picture, but not his own. and he is able to remove his vote, and vote for another.</p> <p>I have PHP to check for all that, and it works fine.</p> <p>The type is 0 is this case</p> <pre><code>function addVote(pictureID, competitionID, type){ $.post('vote.php', {pictureID:pictureID, competitionID:competitionID, vote:1}, function(data){ if (data == 'success') { $("#comp_voteButton_"+pictureID).text('Remove vote'); $("#comp_voteButton_"+pictureID).addClass("alreadyVoted"); $("#comp_voteButton_"+pictureID).attr("onclick", "remVote(" + pictureID + ", " + competitionID + ")") if (type == 0){ $('.button:not(.disabled, #comp_voteButton_'+pictureID+')').text('Only one vote permitted'); $('.button:not(.disabled, #comp_voteButton_'+pictureID+')').removeClass('alreadyVoted'); $('.button:not(.disabled)').addClass('.disabled, .red'); getVote(pictureID, competitionID); }else { $().toastmessage('showErrorToast', "Error!"); } }); </code></pre> <p>}</p> <p>In the same file:</p> <pre><code>function remVote(pictureID, competitionID){ $.post('vote.php', {pictureID:pictureID, competitionID:competitionID, vote:0}, function(data){ if (data == 'success') { $("#comp_voteButton_"+pictureID).text('Vote picture'); $("#comp_voteButton_"+pictureID).attr("onclick", "addVote(" + pictureID +","+competitionID+","+0+")") $("#comp_voteButton_"+pictureID).removeClass('alreadyVoted'); getVote(pictureID, competitionID); }else { $().toastmessage('showErrorToast', "Error!"); } }); </code></pre> <p>}</p> <p>edit: Here's the link if that makes it easier:</p> <pre><code>&lt;a href="javascript:void(0);" class="button blue small" id="comp_voteButton_&lt;?echo $row['ID']?&gt;" onclick="addVote(&lt;?echo $row['ID']?&gt;, &lt;?echo $id?&gt;, &lt;?echo $vote?&gt;)"&gt;Vote&lt;/a&gt; </code></pre> <p>What I want: On addVote all the other buttons should be set to 'onclick(remVote(ID, compID))' - But I can't do that because both the ID's are not fed into the addVote function.</p> <p>I hope you guys get my question (maybe it isn't possible, or a weird work-around has to be made) - But maybe there's a nifty way of doing it.</p>

    1. COSo is the problem that you want to set all of the pictures' onclicks to remove the currently selected vote?

    2. COYes (which is simple enough) - but the toughest part is, when the user then clicks the button (on another picture, it should vote for the picture, and remove the old one)..

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.
