How to Save Image in mysql database using angular2 and php - php

Question

I want to save image inside mysql database. How I can do that using php and angular??
Im using add-style.component.ts to upload image
imageUploadEvent(event){
let imageFile = event.target;
if(imageFile.files.length > 0){
console.log(imageFile.files[0]);
let formData = new FormData();
formData.append('file',imageFile.files[0]);
this._databaseService.insertImageData(formData).subscribe((msg) => {
console.log(msg);
},(error) =>{
console.log("Get Some Error");
console.log(error);
});
}
}
I use add-style.html as following
<div class="container">
<div class="row">
<div class="col s8 offset-2">
<div class="card-panel teal lighten-2">
<h4>Image Uploading</h4>
</div>
<form #imageform ="ngForm">
<input type="file" class="form-file-control" (change)="imageUploadEvent($event)">
<button type="submit" class="btn-lg btn-submit form-control" (click)="saveFormData()" >submit</button>
</form>
</div>
</div>
</div>
I use database.service.ts to call php
insertImageData(value){
return this._http.get("http://localhost/jeleena-api/test-img.php",value).pipe(map(res => {
console.log(res);
}));
}
Following is my php code
<?php
//Create Database Connection
include "db-connection.php";
if(!empty($_FILES['file'])){
$ext = pathinfo($_FILES['file']['name'],PATHINFO_EXTENSION);
$image = time().'.'.$ext;
if(move_uploaded_file($_FILES["file"]["tmp_name"],$image)){
$sql = "INSERT INTO test(img) VALUES('".$image."')";
$conn->query($sql);
echo "successfully uploaded";
}
else{
echo ' error ';
}
}
?>

Ok bear with me. You can use ngStyle for this. https://angular.io/api/common/NgStyle
You need to install the commonsmodule in your ngModule.
Now in your template you can do the following to show the image:
<div [ngStyle]="background-image: url('./assets/images/youImage.jpg');">
Now you are able to show your image based on a url. So what you can do is instead of saving the image to the sql just simple save the ./assets/images/youImage.jpg.
<div [ngStyle]="background-image: url(yourObject.image)>
And to show the image, you can make an object give it a property image and assign the string from the sql.
