Good morning. I'm trying to make the form submission of a message more fluid avoiding the reload of the page for the sending of it. Since the message may be text or image, I need to send both of them to a PHP page for upload. I'm using this code in the html page:
<form id="newmessage" enctype="multipart/form-data">
<textarea form="newmessage" id="messagetext" name="messagetext" ></textarea>
<input type="submit" name="submit" value="send" onclick="return newMessage();">
<input type="file" accept="image/*" id="image" name="image">
</form>
<script>
function newMessage(){
var messagetext = document.getElementById("messagetext").value;
var image = document.getElementById("image").value;
$.ajax({
type:"post",
url:"new_message.php",
data:
{
"messagetext" :messagetext,
"image" :image,
},
cache:false,
success: function(html) {
document.getElementById("messagetext").value = "";
}
});
return false;
}
</script>
As you can see, I'm allowing users to type in the textarea or upload a file. When they submit the form, the newMessage() method is invoked and sends image and messagetext to new_message.php, which process them:
// new_message.php
$messagetext = $_POST["messagetext"];
$image = $_FILES["image"]["tmp_name"];
if((!empty($messagetext) || isset($image))) {
if(!empty($messagetext)) {
// create text message
} else if(isset($image)) {
// create image message
}
}
When I write a text message it works perfectly, but it doesn't send anything if it's image. Maybe the image variable in AJAX is not taking the file properly. I excuse if this question is unclear, but I'm a beginner in StackOverlow and I'm open to edits. Thanks for all replies.
can you try this. you don't need to worry about the file and message in textarea. Make sure you have added jQuery.
$("#newmessage").on("submit", function(ev) {
ev.preventDefault(); // Prevent browser default submit.
var formData = new FormData(this);
$.ajax({
url: "new_message.php",
type: "POST",
data: formData,
success: function (msg) {
document.getElementById("messagetext").value = "";
},
cache: false,
contentType: false,
processData: false
});
return false;
});
