在fpdf单元格上添加换行符 [英] Adding linebreak on fpdf cells

问题描述

我必须添加换行符才能使图像彼此出现.我已经尝试了以下方法，但是它不起作用.

I must add a linebreak for my images to appear after each other. I have tried the following but it does not work.

$rs['imagepath'] = $imagepath;
    $pdf->Image("{$imagepath}\n");

下面是输出图像的原始代码，但是只输出第一个索引，而第二个和第三个图像却不显示...:(

The original code to output the images is below, but it outputs only the first index and the second and third images does not come up... :(

$rs['imagepath'] = $imagepath;
    $pdf->Image("{$imagepath}");

结果在如下所示的foreach循环中:

The result is in a foreach loop like this:

     foreach($select as $index => $rs) 
{    
        $rs['imagepath'] = $imagepath;
        $pdf->Image("{$imagepath}"); 
}

推荐答案

我认为您的代码有误，请尝试下面的代码遍历$rs数组.在当前代码中，您的$imagepath变量始终保持不变.然后可以将\n字符打印到pdf以打印新行

I think your code has a mistake, try the below code to iterate over the $rs array. in the current code, your $imagepath variable is always remain same. you can then print a \n characters to pdf for printing new lines

foreach($select as $index => $rs) 
{    
        $imagepath = $rs['imagepath'];
        $pdf->Image("{$imagepath}"); 
}

我在另一个堆栈溢出线程上发现了这一点

如果您使用的是fpdf，为了能够使用换行符，您将需要使用如

If you are using fpdf, in order to be able to use line breaks you will need to use a multi-line text cell as described here.

如果使用此选项，则应正确解释和转换文本中的换行符.

If you use this, then line breaks in your text should be interpreted and converted correctly.

一个简单的例子:

$pdf->Multicell(0,2,"This is a multi-line text string\nNew line\nNew line"); 

在这里，2是多行文本框的高度.我不知道测量的单位是什么，或者您是否可以将其设置为0并忽略它.如果一开始不起作用，也许可以尝试大量使用.

Here, 2 is the height of the multi-line text box. I don't know what units that's measured in or if you can just set it to 0 and ignore it. Perhaps try it with a large number if at first, it doesn't work.
