我的PHP文件中有几个函数来处理图像上传
3调整大小的函数工作正常，但没有： watermark_image 。代码与其他resize-and-watermark函数的代码完全相同，但它只将SRC存储在我的数据库中，而不是目录中的图像文件本身。
我已经尝试更改所有变量名称（因为就像我说的，它们完全相同，但在不同的方法中），但这不起作用。
我在这里缺少什么？
要清楚，问题在于将新的已调整大小的图像保存在目录中，而不是在图像上放置水印。
resize_big函数与watermark_image函数完全相同，除了图像的大小。水印为135×38px。
形式：
<form action="" method="POST" enctype="multipart/form-data" style="background-color:white; margin-top:100px;">
<div>
<select name="category">
<option value="paard" selected>Paarden</option>
<option value="hond">Honden</option>
<option value="mens">Mensen</option>
<option value="eigen">Eigen werk</option>
</select><br/>
<input type="file" name="files[]" multiple id="file"/><Br/>
Model: <input type="text" name="model" id="model"/>
<br/>
<label class="radio">Portfoliomateriaal</label>
<input type="radio" name="folio" value="TRUE" /> <span>Ja</span>
<input type="radio" name="folio" value="FALSE" checked /> <span>Nee</span><p>
<input type="submit" value="Upload" id="submit" />
</div>
</form>
