Unable to upload an image in laravel 7

Using Laravel 7, I'm tring to setup a form where a user can edit their details and their image. While trying to upload a PNG or JPG image, I get the following Validation Error:
The image must be an image.
If I try to upload image, I get this error
Call to a member function isvalid() on boolean
And If I remove the validation for image, I get a FatalErrorException:
Call to a member function getClientOriginalExtension() on boolean
which is a helper function provided by Intervention/Image library. This could mean that the image didn't upload at all.
This is my Blade file
1. form role="form" id="updateDetailsForm" method="post" action="{{url('/admin/update-admin-details')}}" enctype="multipart/form-data">

Google+ API CommentActivity return 400 Error

I'm having no luck calling the Google+ API for pushing a CommentActivity moment.
I have been able to push an AddActivity successfully as well as a DiscoverActivity.
I read somewhere on the internet whilst searching for a solution that the 400 HTTP Status represents that my user credentials are invalid, but I have been able to post AddActivity & DiscoverActivity after trying CommentActivity and I have tried disconnecting and reconnecting my account and linking the required credentials to no avail.
Here's my code to generate the moment, I believe this is the error, and it's probably something to do with the use of a Target and a Result in this moment type (Neither DiscoverActivity nor AddActivity have a Result field). In particular, the Target's and Result's URLs are the same but the Result's has an appended anchor. The documentation implies that this should work fine, however.
$moment = new Google_Moment();
$moment->setType("http://schemas.google.com/CommentActivity");
$target = new Google_ItemScope();
$target->setUrl(get_permalink($comment->comment_post_id));
$target->setType("http://schema.org/Article");
$moment->setTarget($target);
$result = new Google_ItemScope();
$result->setId("comment-".$comment_id);
$result->setType("http://schema.org/Comment");
$result->setUrl(get_comment_link($comment_id));
$result->setText($comment->comment_content);
$moment->setResult($result);
Soci_Base::getSocial("google")->getUser($user)->GPlus->moments->insert('me', 'vault', $moment);
GPlus is a reference to a Google_PlusService object.
Here's my exception I receive with stack trace (Pointless parts of the files are omitted, hooks.php and plugin.php are not the Google+ API)
Fatal error: Uncaught exception 'Google_ServiceException' with message 'Error calling POST https://www.googleapis.com/plus/v1/people/me/moments/vault?key=AIzaSyBa27u5PtBgFHO4SY_Fq9_0sO39pFWrRzE: (400) Invalid Value' in /~/src/io/Google_REST.php:66 Stack trace:

I think that's all of the info I have on the matter - I have no idea to get the exact HTTP request the script makes.
Thank you in advance for any and all help and for even having a look ^_^

Magento 1.7 Cannot send headers; headers already sent in

SOLVED
I solved this issue with Jonathan Hussey help
I changed this line:
$mModel->getCollection()->load($mId)->getData();
for this:
$mModel->getCollection()->addFieldToFilter('met_id',$Id)->getSelect();
Problem
I created custom module which added tab to admin product page with additional text field.
When I try save this product I get this error:
a:5:{i:0;s:140:"Cannot send headers; headers already sent in /home/nano/domains/mydomain/public_html/gw/lib/Varien/Data/Collection/Db.php, line 693";i:1;s:1630:"#0 /home/nano/domains/mydomain/public_html/gw/lib/Zend/Controller/Response/Abstract.php(148): Zend_Controller_Response_Abstract->canSendHeaders(true)...
I saw that this error created in Observer.php:
$mId = $collection['m_id'];
$mModel->getCollection()->load($mId)->getData(); <-- this line give an error
$data['met_id'] = $mId;
$data['product_id'] = $product->getId();
$data['metf1'] = $this->_getRequest()->getPost('f1');
$mModel->setData($data);
$mModel->save();
Do you have any ideas how fix this ?
EDIT
content of admin template tab file:
<?php
$product = Mage::registry('current_product');
$mItem = Mage::getModel('mmodel/mmodel')->getCollection()->
addFilter('product_id',$product->getId())->getFirstItem();
echo '<div class="input-field">
<label for="f1">File</label>
<input type="text" class="input-text" name="f1" id="f1" value='.$mItem['f1'].' />
</div>';

When working with collections you should only pass arguments to ->load() if you want the SQL for that collection to be logged or output. If you don't want the collection to return all items you can pull the select object from the collection with ->getSelect() and filter with standard Zend methods this way.
If you trace back your collection command you will see because you pass an argument it echo's out the collection SQL.
$mModel->getCollection()->load($mId)->getData();
Have a look at lib/Varien/Data/Collection/Db.php as per the error message and find the load() method. You will see that it accepts two aguments, $printQuery and $logQuery, you have passed an argument to $printQuery. A few lines down in the method you see:
$this->printLogQuery($printQuery, $logQuery);
Looking at the printLogQuery() method you will see that anything passed as the $printQuery argument which evaluates to true triggers the echo on line 693 as per the error message:
echo is_null($sql) ? $this->getSelect()->__toString() : $sql;
This is what is sending headers in your case. Remove the argument from ->load() or pass false and it should fix your problem.

Eclipse gives an exception (org.eclipse.core.runtime.CoreException)

Sometimes when I try to start eclipse it gives me an exception.
I am using Eclipse Juno and in this case using the PHP plug in on a mac with OSX 10.8
I tried to remove some recently installed packages, but the Error still appears,
The wierd thing is that this exception is not always given. Somtimes it just works but this is most of the time not the case
The full stack trace is given below.
org.eclipse.core.runtime.CoreException: Plug-in org.eclipse.php.ui was unable to load class org.eclipse.php.internal.ui.explorer.PHPExplorerPart.

Could someone help me with this problem?
It gets pretty annoying

The following sequence should solve the issue
Go to the place where your projects are stored (workspace)
Search for the \.metadata\.plugins folder
Delete any *.dat file
Re-start Eclipse
