use AND operator 

if(is_uploaded_file($this->request->data['Home']['image_1']['tmp_name']) &&

else{//Img not uploaded
 //HERE YOUR part You had WHEN image is NOT Uploaded
}

//Updated as per Your issue-> SEE , check 1st ELSE IF :

else if(is_uploaded_file($this->request->data['Home']['image_1']['tmp_name']) &&
        is_uploaded_file($this->request->data['Home']['image_3']['tmp_name']) 
  )
{
 //NOW u  hav VALUES FOR `image_1` AND `image_3` OK ?  BUT `image_2` val missing.SO set OLD VALUE from database 
 $tourForImg = $this->Home->findByid($id);
 $this->request->data['Home']['image_2'] = $tourForImg['Home']['image_2'];
}

Now for next else if(is_uploaded_file($this->request->data['Home']['image_1']['tmp_name']) && is_uploaded_file($this->request->data['Home']['image_2']['tmp_name']) ) { //NOW u hav VALUES FOR image_1 AND image_2 OK ? BUT image_3 val missing.SO set OLD VALUE from database $tourForImg = $this->Home->findByid($id); $this->request->data['Home']['image_3'] = $tourForImg['Home']['image_3']; }

DO SAME FOR -> if image1 is only uploaded Then set OLD values of image2 & image3 from DATABASE

Do same for image2 only uploaded

Do same for image3 only uploaded .

GETTNG? use your own logic dude.




回答2:


First use before all if conditions

$tourForImg = $this->Home->findByid($id);

Use if else loop for each if case in this way

// for image_1
if(yourconditions for image 1)
{
    // Your code
    $uploaded = true;
}
else
{
    $this->request->data['Home']['image_1'] = $tourForImg['Home']['image_1'];
    $uploaded = false;
}

you can also set a variable uploaded to check in end if no image was uploaded at all or you can also set count of images uploaded using $uploaded ++;
