Question

我有这段代码：

<?php
   $imageVar = $entry->field('logo')->generate();
   $path = $imageVar;
   $file = basename($path, ".svg");
   $rest = substr($file, 0, -9);
?>

<img src="<?php echo $imageVar; ?>" onerror="this.onerror=null; this.src='files/media/images/partners/<?php echo $rest; ?>.png'" title="<?php echo $entry->field('name')->value(); ?>" alt="<?php echo $entry->field('name')->value(); ?>" >

它的工作但我收到这样的错误：

但我不知道如何解决这个问题。

首先，你应该理解对象和字符串之间的差异

$imageVar = $entry->field('logo')->generate();
            $path = $imageVar;

这里$ imageVar变成了对象而不是字符串所以你改变了第一个bez 你的函数$ file = basename（$ path，＆＃34; .svg＆＃34;）;需要字符串而不是对象

如果你在php中这样做，那么使用（字符串）befour $ imageVar现在你的代码将是

 $imageVar = $entry->field('logo')->generate();
                $path = (string)$imageVar;

试

将PHP对象转换为字符串
