in my controller i have an array which i have populated from my database and stored which looks like this and is called dataset2
array(2) {
["April"]=> int(92)
["May"]=> int(86)
}
In my view i can dd{{}} on the array and see this is the structure.
Now I want to convert it into a javascript array so i can use flot to make it into a graph.
my Javascript within my view looks like this
<script language="javascript" type="text/javascript">
$(function () {
var data1 = [
["April", 13],
["May", 20],
];
var data2 = [<?php echo json_encode($dataset2 );?>];
$.plot("#placeholder", [{
data: data1,
label: "NewBeach"
}, {
data: data2,
label: "Sandhills"
}], {
series: {
lines: { show: true },
points: {
show: true,
barWidth: 0.1,
align: "center"
}
},
xaxis: {
mode: "categories"
},
yaxis: {
},
grid: {
hoverable: true,
clickable: true
}
});
});
</script>
Am i missing something when converting it?, as it doesnt draw anything with the JSON_encode array but does with the hard coded one. From what i have read it seems as though thats all i need. Is it because of the values within my array?
Kind regards Mike
you have already done it: var data2 = ; just remove the brackets [ ]
also assign key to your array e.g. array('key'=>'value')
$array = array(label=>value, name=>value);
var data2 = <?php echo json_encode($dataset2 );?>;
As an alternative to the other answers - you could consider using a package for this. Jeffrey Way from Laracasts made this package laracasts/PHP-Vars-To-Js-Transformer
JavaScript::put('data2', $dataset2);
