I've learned how to use AJAX, PHP and MySql to return database values but how do you handle multiple values?
Does AJAX.lastvalue return an array or is there something I have to do to receive multiple values?
In PHP do I have to do something special or simply;
echo $var1 echo $var2[/code:2vyw9z40]
I cant say you what happens, but I can say you how you can try:
--AJAX On "yourTag" completed
-->Browser Log in console AJAX.LastData
You have to experiment a bit.
You can return a tokenized string or a JSON object that C2 can interpret.
Develop games in your browser. Powerful, performant & highly capable.
Could you possibly give me a small example and I'll work the rest out from there, thanks Magi
Make your PHP script to return a concatenated line like
echo $var1 . "|" . $var2[/code:2yudkrsv] ( the dot "." should be the way to concatenate in PHP IIRC, to make sure, be sure to look into the PHP manual or a website about PHP programming). When you receive your AJAX line you can use the [url=https://www.scirra.com/manual/126/system-expressions]system expressions[/url] "tokenat", "tokencount", etc... to manipulate the string, according to the separator (in my example the "|" character). tokenat(AJAX.lastdata,0,"|") should allow you to only retrieve $var1; tokenat(AJAX.lastdata,1,"|") => $var2
Multible values by json:
Multi row:
$arr = array(); while($row = mysqli_fetch_array($result,MYSQLI_ASSOC)) { arr[] = $row; } echo json_encode($arr); [/code:hfj250k1] AJAX.LastData -> [{"name":"Bob","secondName":"Meyer","isMember":1},{"name":"Dieter","secondName":"Miller","isMember":1}] [img="https://dl.dropboxusercontent.com/u/95601836/multiphp2json.png"] Single row(first result): [code:hfj250k1] $arr = array(); while($row = mysqli_fetch_array($result,MYSQLI_ASSOC)) { arr[] = $row; } echo json_encode($row[0]); [/code:hfj250k1] AJAX.LastData -> {"name":"Bob","secondName":"Meyer","isMember":1} [img="https://dl.dropboxusercontent.com/u/95601836/singlephp2json.png"] Then use a json plugin to work with this strings. For example: [url=https://www.scirra.com/forum/plugin-tools-object-array-in-construct-based-on-json_t147493]Tools[/url] Some examples: [img="https://dl.dropboxusercontent.com/u/95601836/getLastData.png"] Sorry for spam, but my server is down and i am boring...
Thank you for all the help, I got my code working and managed to edit it to what I wanted.
Great help again, thank you.
