I'm trying to save the pasted image into a folder and the relevant details to the database, but my current code is not saving the pasted image, I try to put a hard coded url on the src attribute and it was working.
I inspect element of the src of the pasted image and it was very long, like this "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAARIAAAC4CAYAAAAvx2MfAAAgAElEQVR4Ae2dCXwW1dX..." its longer than this but for sample purposes. How should I save the image using this image address? Please help.
Here is the HTML:
<div class="col-lg-6">
<div class="form-group col-lg-12">
<input class="form-control" id="pasteArea" placeholder="Paste image here..."></input>
<img name="map-sketch" id="pastedImage" width="100%" height="100%" src='images/sample.png'></img>
</div>
</div>
<div class="col-lg-1">
<button type="button" class="btn btn-primary" onclick="save()">Save</button>
</div>
<div class="col-lg-2" id="saving-info"></div>
The src of the image above is a hard coded url.
Here is the javascript onpaste that I'm using:
document.getElementById('pasteArea').onpaste = function (event) {
var items = (event.clipboardData || event.originalEvent.clipboardData).items;
console.log(JSON.stringify(items)); // will give you the mime types
var blob = null;
for (var i = 0; i < items.length; i++) {
if (items[i].type.indexOf("image") === 0) {
blob = items[i].getAsFile();
}
}
if (blob !== null) {
var reader = new FileReader();
reader.onload = function(event) {
console.log(event.target.result); // data url!
document.getElementById("pastedImage").src = event.target.result;
};
reader.readAsDataURL(blob);
}
}
And here is the AJAX code:
function save(){
var params = 'kind=land';
var image = document.getElementById("pastedImage").getAttribute("src");
params += '&image='+image;
if (window.XMLHttpRequest) {
// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp = new XMLHttpRequest();
} else { // code for IE6, IE5
xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange = function () {
if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
document.getElementById("saving-info").innerHTML = xmlhttp.responseText;
}else { // waiting for result
document.getElementById('saving-info').innerHTML = '<img src="../images/ajax_loader.gif">';
}
}
xmlhttp.open("POST", "../functions/save-faas.php", true);
xmlhttp.setRequestHeader("Content-Type","application/x-www-form-urlencoded");
xmlhttp.send(params);
}
And here is the PHP code for saving the image:
<?php
$url = $image;
$img = '../images/1.png';
file_put_contents($img,file_get_contents($url));
?>
The code here is working with hard coded URL but not for pasted image.
What should I do? Thanks.
