    <p>I am using $.ajax to get a JSON response from a php script. if i log the data variable from the $.ajax success function it outputs a properly formatted JSON object, however when I try to access properties of the data var it's undefined. here is the php the is being sent back:</p> <pre><code>echo json_encode(array("status"=&gt;true, "success"=&gt;"Login Success", "message"=&gt;"You have been logged in successfully.")); </code></pre> <p>and here is my ajax call:</p> <pre><code>$.ajax({ type: "POST", data: { login: true, username: $('#login-username').val(), password: $('#login-password').val() }, async: false, url: "./php/client-login.php", success: function (data) { console.log(data.status); if (data.status) { console.log(data.success); displayModal(data.success, data.message, "./js/login-modal-code.js"); } else if (!data.status) { displayModal(data.error, data.message, "./js/login-modal-code.js"); } }, error: function (jqXHR, status, responseText) { console.log(status); } }); </code></pre> <p>if i add the <code>dataType: "json"</code> option to the $.ajax call I get a parse error and if i try to do <code>$.parseJSON(data);</code> to access the data in the data var I get and unexpected token error. I'm not really sure what I'm doing wrong, I've used this setup before and it always has worked before but for some reason it isn't now. anyone see where i've gone wrong?</p> <p>EDIT: forgot to mention here is the response from the php script: </p> <p><code>{"status":true,"success":"Login Success","message":"You have been logged in successfully."}</code></p> <p>EDIT 2: Here is a screen of my console. the top .length call is the json that was logged from <code>console.log(data)</code> and the bottom one is from the response in chrome dev tools network tab for the response from the php script. they line up perfectly yet the second is showing a length of 93, how can i fix this? <img src="https://i.stack.imgur.com/5nHMB.png" alt="Console Image"></p>

    1. COAt a guess I'd say your PHP script is including something unexpected in the output, like a blank line.

    2. COWhitespace shouldn't cause a problem with parsing JSON, but I suspect some other character is slipping through and you're not seeing it.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
