  1. POCode Igniter php - return (ajax?) data based on dropdown selection with JQuery
    text
    copied!<p>I want to generate some data for editing, filtered by the choice a user makes in a dropdown menu, but I don't want to complicate things. </p> <p>I already have my project querying the database for a list of "trees", and populating a dropbox with the tree name, assigning the tree_id as its value.</p> <p>All I want to do is, when the user makes a choice in the drop-down, have JQuery return a list of only that ID's relevant data (description, etc). </p> <p>What's the simplest way to do that? Do I even need to make an AJAX request? Here's my code:</p> <p>CONTROLLER:</p> <pre><code>$this-&gt;load-&gt;model('Model_form','', TRUE); $data['trees'] = $this-&gt;Model_form-&gt;get_tree(); $this-&gt;load-&gt;view('view_form_tree', $data); </code></pre> <p>MODEL:</p> <pre><code>function get_tree(){ $query = $this-&gt;db-&gt;query('SELECT * FROM trees'); return $query-&gt;result(); } </code></pre> <p>VIEW:</p> <pre><code>&lt;h1&gt;Edit Tree&lt;/h1&gt; &lt;select id="f_treeindex" name="f_treeindex" class="dd_black"&gt; &lt;option value=""&gt;&lt;/option&gt; &lt;?php foreach($trees as $tree){ echo '&lt;option value="' . $tree-&gt;id . '"&gt;' . $tree-&gt;tree_name . '&lt;/option&gt;'; } ?&gt; &lt;/select&gt; &lt;script type="text/javascript"&gt; $(document).ready(function() { $('#f_treeindex').change(function(){ var tree_id = $('#f_treeindex').val(); if (tree_id != ""){ //DO WHATEVER I NEED TO DO TO CALL THE INFORMATION FOR THE TREE WHOSE ID MATCHES THAT SELECTED IN THE DROPDOWN }//end if }); //end change }); //end docready &lt;/script&gt; </code></pre> <p>Just a note that the SELECT * statement in the model will return the tree_id, tree_name, and tree_description.</p>
