<div class="admonition note">
<p class="first admonition-title">Note</p>
<p>From MongoDB.org:</p>
<p class="last">MongoDB supports a &quot;find, modify, and return&quot; command. This command
can be used to atomically modify a document (at most one) and
return it. Note that, by default, the document returned will not
include the modifications made on the update.</p>
</div>
<p>Doctrine fully integrates the find and modify functionality to the
query builder object so you can easily run these types of queries!</p>
<div class="section" id="update">
<h2>Update<a class="headerlink" href="#update" title="Permalink to this headline"></a></h2>
<p>For example you can update a job and return it:</p>
<div class="highlight-php"><div class="highlight"><pre><span class="cp">&lt;?php</span>
<span class="nv">$job</span> <span class="o">=</span> <span class="nv">$dm</span><span class="o">-&gt;</span><span class="na">createQueryBuilder</span><span class="p">(</span><span class="s1">&#39;Job&#39;</span><span class="p">)</span>
<span class="c1">// Find the job</span>
<span class="o">-&gt;</span><span class="na">findAndUpdate</span><span class="p">()</span>
<span class="o">-&gt;</span><span class="na">field</span><span class="p">(</span><span class="s1">&#39;in_progress&#39;</span><span class="p">)</span><span class="o">-&gt;</span><span class="na">equals</span><span class="p">(</span><span class="k">false</span><span class="p">)</span>
<span class="o">-&gt;</span><span class="na">sort</span><span class="p">(</span><span class="s1">&#39;priority&#39;</span><span class="p">,</span> <span class="s1">&#39;desc&#39;</span><span class="p">)</span>
<span class="c1">// Update found job</span>
<span class="o">-&gt;</span><span class="na">field</span><span class="p">(</span><span class="s1">&#39;started&#39;</span><span class="p">)</span><span class="o">-&gt;</span><span class="na">set</span><span class="p">(</span><span class="k">new</span> <span class="nx">\MongoDate</span><span class="p">())</span>
<span class="o">-&gt;</span><span class="na">field</span><span class="p">(</span><span class="s1">&#39;in_progress&#39;</span><span class="p">)</span><span class="o">-&gt;</span><span class="na">set</span><span class="p">(</span><span class="k">true</span><span class="p">)</span>
<span class="o">-&gt;</span><span class="na">getQuery</span><span class="p">()</span>
<span class="o">-&gt;</span><span class="na">execute</span><span class="p">();</span>
</pre></div>
</div>
<p>If you want to update a job and return the new document you can
call the <code class="docutils literal"><span class="pre">returnNew()</span></code> method.</p>
<p>Here is an example where we return the new updated job document:</p>
<div class="highlight-php"><div class="highlight"><pre><span class="cp">&lt;?php</span>
<span class="nv">$job</span> <span class="o">=</span> <span class="nv">$dm</span><span class="o">-&gt;</span><span class="na">createQueryBuilder</span><span class="p">(</span><span class="s1">&#39;Job&#39;</span><span class="p">)</span>
<span class="c1">// Find the job</span>
<span class="o">-&gt;</span><span class="na">findAndUpdate</span><span class="p">()</span>
<span class="o">-&gt;</span><span class="na">returnNew</span><span class="p">()</span>
<span class="o">-&gt;</span><span class="na">field</span><span class="p">(</span><span class="s1">&#39;in_progress&#39;</span><span class="p">)</span><span class="o">-&gt;</span><span class="na">equals</span><span class="p">(</span><span class="k">false</span><span class="p">)</span>
<span class="o">-&gt;</span><span class="na">sort</span><span class="p">(</span><span class="s1">&#39;priority&#39;</span><span class="p">,</span> <span class="s1">&#39;desc&#39;</span><span class="p">)</span>
<span class="c1">// Update found job</span>
<span class="o">-&gt;</span><span class="na">field</span><span class="p">(</span><span class="s1">&#39;started&#39;</span><span class="p">)</span><span class="o">-&gt;</span><span class="na">set</span><span class="p">(</span><span class="k">new</span> <span class="nx">\MongoDate</span><span class="p">())</span>
<span class="o">-&gt;</span><span class="na">field</span><span class="p">(</span><span class="s1">&#39;in_progress&#39;</span><span class="p">)</span><span class="o">-&gt;</span><span class="na">set</span><span class="p">(</span><span class="k">true</span><span class="p">)</span>
<span class="o">-&gt;</span><span class="na">getQuery</span><span class="p">()</span>
<span class="o">-&gt;</span><span class="na">execute</span><span class="p">();</span>
</pre></div>
</div>
<p>The returned <code class="docutils literal"><span class="pre">$job</span></code> will be a managed <code class="docutils literal"><span class="pre">Job</span></code> instance with the
<code class="docutils literal"><span class="pre">started</span></code> and <code class="docutils literal"><span class="pre">in_progress</span></code> fields updated.</p>
</div>
<div class="section" id="remove">
<h2>Remove<a class="headerlink" href="#remove" title="Permalink to this headline"></a></h2>
<p>You can also remove a document and return it:</p>
<div class="highlight-php"><div class="highlight"><pre><span class="cp">&lt;?php</span>
<span class="nv">$job</span> <span class="o">=</span> <span class="nv">$dm</span><span class="o">-&gt;</span><span class="na">createQueryBuilder</span><span class="p">(</span><span class="s1">&#39;Job&#39;</span><span class="p">)</span>
<span class="o">-&gt;</span><span class="na">findAndRemove</span><span class="p">()</span>
<span class="o">-&gt;</span><span class="na">sort</span><span class="p">(</span><span class="s1">&#39;priority&#39;</span><span class="p">,</span> <span class="s1">&#39;desc&#39;</span><span class="p">)</span>
<span class="o">-&gt;</span><span class="na">getQuery</span><span class="p">()</span>
<span class="o">-&gt;</span><span class="na">execute</span><span class="p">();</span>
</pre></div>
</div>
<p>You can read more about the find and modify functionality on the
<a class="reference external" href="https://docs.mongodb.com/manual/reference/method/db.collection.findAndModify/">MongoDB website</a>.</p>
<div class="admonition note">
<p class="first admonition-title">Note</p>
<p class="last">If you don't need to return the document, you can use just run a normal update which can
affect multiple documents, as well. For multiple update to happen you need to use
<code class="docutils literal"><span class="pre">-&gt;updateMany()</span></code> method of the builder (or <code class="docutils literal"><span class="pre">update()-&gt;multiple()</span></code> combination that
was deprecated in version 1.2).</p>
