    <p>I create an object in Javascript to pass as the argument to a PHP script.</p> <pre><code>var pattern = new Object(); pattern['@id'] = ''; pattern['@num'] = ''; pattern.cprop = new Object(); //pattern.aprop = new Object(); pattern['@id'] = id; pattern['@num'] = pn; pattern.cprop.$ = pb.find('input[name="subject"]').val() || ''; var json = {'pattern': pattern}; </code></pre> <p>My Ajax call is</p> <pre><code>url: clr_url_base+'storepat.php?data='+encodeURIComponent($.toJSON(json)) </code></pre> <p>In my PHP script, I use</p> <pre><code>$pat = json_decode(str_replace ('\"','"', $data), true); $prep = $pat["pattern"]["@id"]; $sense = $pat["pattern"]["@num"]; $cprop = $pat["pattern"]["cprop"]["$"]; //$aprop = $pat["pattern"]["aprop"]["$"]; </code></pre> <p>This works, but when I add the <strong>aprop</strong> value, it no longer works.All values are strings. Any suggestions as to what's going wrong.</p> <p>Here are the two JSON strings:</p> <pre><code>{\"pattern\":{\"@id\":\"against\",\"@num\":\"1(1)\",\"cprop\":{\"$\":\"a person or thing (often abstract) opposed\"}}} {\"pattern\":{\"@id\":\"against\",\"@num\":\"1(1)\",\"cprop\":{\"$\":\"a person or thing (often abstract) opposed\"},\"aprop\":{\"$\":\"verbs (to which \'against\' introduces idea of opposition); nouns denoting conflict\"}}} </code></pre> <p>The first has only has the value for <strong>cprop</strong>, while the second adds the value for <strong>aprop</strong>. Note that <strong>aprop</strong> has single-quotes. It is this kind of data that seems to beg for encoding in the Javascript and decoding in the PHP. The second bombs. I have some 20 fields from a form, so it would get quite complex to create the JSON by hand, rather than as fields in <strong>pattern</strong>. When the second bombs, the value of <strong>$pat</strong> is NULL.</p>

    1. COit seems silly to JSON encode data that could easily be part of the query string.

    2. COI think you should post the json data instead of sending it by query string. Just a suggestion :)

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.
