PHPOffice\PHPPresentation 使用Placeholder添加sldNum页码设置字体和页码位置BUG修复以及无法显示页码问题

被PHPPresentation的页码设置折腾了好几天,一直以为是自己的代码写的有问题,先说说目前我遇到的BUG 1.在Master或Slide中设置的Placeholder页码位置和大小无效,生成的PPT Placeholder始终在左上角0,0的位置。 2.为Placeholder设置的字体属性不生效,比如大小,居中等。 3.设置垂直居中需要不可以使用fontAlgn,不生效。 以下是解决方法: 修改文件 PHPOffice/PHPPresentation/src/PhpPresentation/Writer/PowerPoint2007/AbstractSlide.php 找到方法名
protected function writeShapeText(XMLWriter $objWriter, RichText $shape, $shapeId)
1.注释代码 1)找到代码
if (!$shape->isPlaceholder()) {
    // p:sp\p:spPr\a:xfrm
将if一行注释 这里是设置RichText的相关位置的,注释掉就可以将位置信息应用给Placeholder,否则位置在0,0
//if (!$shape->isPlaceholder()) {
    // p:sp\p:spPr\a:xfrm
    ...
//}
2)找到代码
if (!$shape->isPlaceholder()) {
    $verticalAlign = $shape->getActiveParagraph()->getAlignment()->getVertical();
将if一行注释 这里设置的垂直居中,如果不注释掉垂直方向无法设置位置,文字只在顶部
//if (!$shape->isPlaceholder()) {
    $verticalAlign = $shape->getActiveParagraph()->getAlignment()->getVertical();
    ...
//}
2.添加代码 1)找到代码
if ($shape->isPlaceholder() &&
    ($shape->getPlaceholder()->getType() == Placeholder::PH_TYPE_SLIDENUM ||
        $shape->getPlaceholder()->getType() == Placeholder::PH_TYPE_DATETIME)
) {
    $objWriter->startElement('a:p');
在其后添加下面代码,主要是水平居中,margin值得设置等等
//TODO 此处为chenxue4076@163.com手动添加,为了是页码也能够使用到样式
    //TODO 1添加排版信息
    $paragraph =$shape->getActiveParagraph()->getAlignment();
    //a:pPr
    $objWriter->startElement('a:pPr');
        $objWriter->writeAttribute('algn', $paragraph->getHorizontal());
        $objWriter->writeAttribute('fontAlgn', $paragraph->getVertical());
        $objWriter->writeAttribute('marL', CommonDrawing::pixelsToEmu($paragraph->getMarginLeft()));
        $objWriter->writeAttribute('marR', CommonDrawing::pixelsToEmu($paragraph->getMarginRight()));
        $objWriter->writeAttribute('indent', CommonDrawing::pixelsToEmu($paragraph->getIndent()));
        $objWriter->writeAttribute('lvl', $paragraph->getLevel());

        $objWriter->startElement('a:lnSpc');
            $objWriter->startElement('a:spcPct');
                $objWriter->writeAttribute('val', $shape->getActiveParagraph()->getLineSpacing() . "%");
            $objWriter->endElement();
        $objWriter->endElement();
    $objWriter->endElement();
    //TODO 1 END 添加排版信息
//TODO END 此处为chenxue4076@163.com手动添加,为了是页码也能够使用到样式
2)继续往下查找到代码
$objWriter->startElement('a:fld');
$objWriter->writeAttribute('id', $this->getGUID());
$objWriter->writeAttribute('type', (
$shape->getPlaceholder()->getType() == Placeholder::PH_TYPE_SLIDENUM ? 'slidenum' : 'datetime'));
在其后添加下面代码,主要是字体信息,比如加粗,字体类型,大小等信息
//TODO 此处为chenxue4076@163.com手动添加,为了是页码也能够使用到样式
    //TODO 2 添加字体信息
    $font = $shape->getActiveParagraph()->getFont();
    // a:rPr
    $objWriter->startElement('a:rPr');
        $objWriter->writeAttributeIf($font->isBold(), 'b', '1');
        $objWriter->writeAttributeIf($font->isItalic(), 'i', '1');
        $objWriter->writeAttributeIf($font->isStrikethrough(), 'strike', 'sngStrike');
        // Size
        $objWriter->writeAttribute('sz', ($font->getSize() * 100));
        // Character spacing
        $objWriter->writeAttribute('spc', $font->getCharacterSpacing());
        // Underline
        $objWriter->writeAttribute('u', $font->getUnderline());
        // Color - a:solidFill
        $objWriter->startElement('a:solidFill');
            $this->writeColor($objWriter, $font->getColor());
        $objWriter->endElement();
        // Font - a:latin
        $objWriter->startElement('a:latin');
            $objWriter->writeAttribute('typeface', $font->getName());
        $objWriter->endElement();
    // a:rPr
    $objWriter->endElement();
    //TODO 2 添加字体信息
//TODO END 此处为chenxue4076@163.com手动添加,为了是页码也能够使用到样式
经过以上几步设置,现在使用Placehoder 的 sldNum 已经能正常设置文字属性和位置了 下面是生成页码的函数方法,仅供参考

经过以上设置,我们的代码添加页码就和添加其他元素一样简单了。 附件已经打包,可直接将此文件覆盖到原文件,但是不建议这样做,可能因为版本升级代码变化等原因影响到就不好了,附件地址 AbstractSlide.php.zip
