    <p>I can't get my json correctly formatted the way i want/need. I'm using open-flash-charts for this and my graph doesn't accept the json i give it... Everything is done inside the php that open-flash-chart uses as data file. I'm just echoing my json, could this be the problem or json-format style??</p> <pre><code>class Charts { public $title = ["title"=&gt;['text' =&gt; "ae", 'style' =&gt; "za"]]; public $y_legend = ["y_legend"=&gt;['text' =&gt; "", 'style' =&gt; ""]]; public $x_axis = ["x_axis"=&gt;['stroke' =&gt; '1', 'tick_height' =&gt; '10', 'colour' =&gt; "#d000d0", 'grid_colour' =&gt; "#00ff00", 'labels' =&gt; [] ]]; public $y_axis = ["y_axis"=&gt;['stroke' =&gt; '1', 'tick_length' =&gt; '10', 'colour' =&gt; "#d000d0", 'grid_colour' =&gt; "#00ff00", 'offset' =&gt; '0', 'max' =&gt; '20']]; public $bar = ["elements"=&gt;['type' =&gt; "bar", 'alpha' =&gt; '0.5', 'colour' =&gt; '#9933CC', 'text' =&gt; "", 'font-size' =&gt; '10', 'values' =&gt; [] ]]; public $pie = ["elements" =&gt; ['type' =&gt; "pie", 'start_angle' =&gt; '180', 'colours' =&gt; ["#d01f3c","#356aa0","#C79810","#73880A","#D15600","#6BBA70"], 'alpha' =&gt; '0.6', 'stroke' =&gt; '2', 'animate' =&gt; '0', 'values' =&gt; [] ]]; } $a = new Charts(); $a-&gt;title['title']['text'] = "Dates"; $a-&gt;title['title']['style'] = "{font-size: 20px; color:#0000ff; font-family: Verdana; text-align: center;}"; $a-&gt;y_legend['y_legend']['text'] = "Khash/s"; $a-&gt;y_legend['y_legend']['style'] = "{font-size: 10px; color:#0000ff; font-family: Verdana; text-align: center;}"; $a-&gt;x_axis['x_axis']['labels'] = get_val_date($poolstale_enc_json); // Function returns an array of values $a-&gt;bar['elements']['text'] = "barText"; $a-&gt;bar['elements']['values'] = get_val_value($poolstale_enc_json);// Function returns an array of values $all_data = $a-&gt;title; $all_data += $a-&gt;y_legend; $all_data += $a-&gt;x_axis; $all_data += $a-&gt;bar; echo json_encode($all_data); </code></pre> <p>This gives as output:</p> <pre><code>{ "title":{ "text":"Dates", "style":"{font-size: 20px; color:#0000ff; font-family: Verdana; text-align: center;}" }, "y_legend":{ "text":"Khash\/s", "style":"{font-size: 10px; color:#0000ff; font-family: Verdana; text-align: center;}" }, "x_axis":{ "stroke":"1", "tick_height":"10", "colour":"#d000d0", "grid_colour":"#00ff00", "labels":[ "2013-08-25" ] }, "elements":{ "type":"bar", "alpha":"0.5", "colour":"#9933CC", "text":"barText", "font-size":"10", "values":[ "2.96" ] } } </code></pre> <p>but i need to have correct format because my charts won't accept this json. Example correct by their site:</p> <pre><code>{ "title":{ "text":"Many data lines", "style":"{font-size: 30px;}" }, "y_legend":{ "text":"Open Flash Chart", "style":"{font-size: 12px; color:#736AFF;}" }, "elements":[ { "type": "line", "colour": "#9933CC", "text": "Page views", "width": 2, "font-size": 10, "dot-size": 6, "values" : [15,18,19,14,17,18,15,18,17] }, { "type": "line_dot", "colour": "#CC3399", "width": 2, "text": "Downloads", "font-size": 10, "dot-size": 5, "values" : [10,12,14,9,12,13,10,13,12] }, { "type": "line_hollow", "colour": "#80a033", "width": 2, "text": "Bounces", "font-size": 10, "dot-size": 6, "values" : [5,7,9,7,4,6,1,2,5] } ], "y_axis":{ "max": 20 }, "x_axis":{ "steps": 2, "labels": ["January","February","March","April","May","June","July","August","September"] } } </code></pre>

    1. COLook at the JSON. Everything in `[]` is an array. Everything in `{}` an object. Now change your PHP to match that or implement http://php.net/JSONSerializable.

    2. CO@user2489680 "I can't get my json correctly formatted the way i want/need. I'm using open-flash-charts for this and my graph doesn't accept the json i give it." try to bruteforce every combination for the JSON strings untill it accept your JSON.... (yes Sarcasm) and you dont even name your "open-flash-charts" start with that information first because Google gives only 75.700.000 results ..

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.
