Question

我有这个用PHP制作的代码，我用<<<HTML使用变量$ style集成了一个css代码，这个样式在图像背面显示了3次，我怀疑它出现了3次因为图片的数量，我希望只出现一次。

我不知道图像数量显示的是什么？！

<?php
if( ! defined( 'CMSFUTURE' ) ) {
    die( "Hacking attempt!" );
}
$style = <<<HTML
<style>
.gallerypro{padding:5px 5px 0 5px;height: 120px; width: 543px; background-color: rgb(220,220,220); border:1px solid grey; box-shadow: 7px 8px 20px -5px rgba(0,0,0,0.47);}
</style>
HTML;
$distr_charset = "utf-8";
$self_id ='';
$homeUrl = $config['http_home_url'];
$rootPath = $_SERVER['DOCUMENT_ROOT'];
$fullpath = $rootPath."/uploads/jmgallery/";
include ('engine/api/api.class.php');
if($dle_module == "showfull") {
$id = $_GET['newsid'];
$getCg = $dle_api->load_table($table="dle_jmgallery", $fields="id", $where="id > 0", $multirow="false", $start="0", $limit="0", $sort="", $sort_order="");
$having = FALSE;
  foreach($getCg as $g){
    if($g['id'] == $id){$having = TRUE;}
  }
if($having == TRUE){
$getGal = $dle_api->load_table($table="dle_jmgallery", $fields="*", $where="id > 0", $multirow="true", $start="0", $limit="0", $sort="", $sort_order="");
  foreach($getGal as $carousel){
      $sizeW = $carousel['sizew'];
      $sizeH = $carousel['sizeh'];
      $dist = $carousel['distance']; 
      $self_id = $carousel['id'];    
      if($self_id == $id){
        $mask = "*.jpg";
        $idN = $fullpath.$id."/";
        $mask = $idN.$mask;
        if($sizeH == "0"){$sizeH = $sizeW; }
        foreach (glob($mask) as $filename) {
          $fileRname = substr($filename, -14);
          $picSizeW = $sizeW * 2;
          $img = "<img src='/uploads/jmgallery/$id/$fileRname' width='".$picSizeW."px' />";
          $galery .= "$style<div class='gallerypro'><a style='overflow:hidden; display:block; float:left; margin:".$dist."px 0 0 ".$dist."px; width:".$sizeW."px; height:".$sizeH."px;'  href='".$homeUrl."uploads/jmgallery/$id/$fileRname' onclick='return hs.expand(this)'>$img</a>"; } $xJ ="Computer repair"; $xJ = iconv("UTF-8", "UTF-8", $xJ); $galery .="<a href='$sitename' style='display:none; '>$xJ</a></div>";
          echo $galery."<br clear='left' />";
      }
    }
  }
  $having = FALSE;
}
?>

这是我得到的结果： enter image description here

在图片的背景中看到？该样式来自上面声明的变量$ style，用于：

$galery .= "$style<div class='gallerypro'><a style='overflow:hidden; display:block; float:left; margin:".$dist."px 0 0 ".$dist."px; width:".$sizeW."px; height:".$sizeH."px;'  href='".$homeUrl."uploads/jmgallery/$id/$fileRname' onclick='return hs.expand(this)'>$img</a>"; } $xJ ="Computer repair"; $xJ = iconv("UTF-8", "UTF-8", $xJ); $galery .="<a href='$sitename' style='display:none; '>$xJ</a></div>";

将<?php if( ! defined( 'CMSFUTURE' ) ) { die( "Hacking attempt!" ); } $style = <<<HTML <style> .gallerypro{padding:5px 5px 0 5px;height: 120px; width: 543px; background-color: rgb(220,220,220); border:1px solid grey; box-shadow: 7px 8px 20px -5px rgba(0,0,0,0.47);} </style> HTML; $distr_charset = "utf-8"; $self_id =''; $homeUrl = $config['http_home_url']; $rootPath = $_SERVER['DOCUMENT_ROOT']; $fullpath = $rootPath."/uploads/jmgallery/"; include ('engine/api/api.class.php'); if($dle_module == "showfull") { $id = $_GET['newsid']; $getCg = $dle_api->load_table($table="dle_jmgallery", $fields="id", $where="id > 0", $multirow="false", $start="0", $limit="0", $sort="", $sort_order=""); $having = FALSE; foreach($getCg as $g){ if($g['id'] == $id){$having = TRUE;} } if($having == TRUE){ $getGal = $dle_api->load_table($table="dle_jmgallery", $fields="*", $where="id > 0", $multirow="true", $start="0", $limit="0", $sort="", $sort_order=""); $galerry = $style."<div class='gallerypro'>"; foreach($getGal as $carousel){ $sizeW = $carousel['sizew']; $sizeH = $carousel['sizeh']; $dist = $carousel['distance']; $self_id = $carousel['id']; if($self_id == $id){ $mask = "*.jpg"; $idN = $fullpath.$id."/"; $mask = $idN.$mask; if($sizeH == "0"){$sizeH = $sizeW; } foreach (glob($mask) as $filename) { $fileRname = substr($filename, -14); $picSizeW = $sizeW * 2; $img = "<img src='/uploads/jmgallery/$id/$fileRname' width='".$picSizeW."px' />"; $galery .= "<a style='overflow:hidden; display:block; float:left; margin:".$dist."px 0 0 ".$dist."px; width:".$sizeW."px; height:".$sizeH."px;' href='".$homeUrl."uploads/jmgallery/$id/$fileRname' onclick='return hs.expand(this)'>$img</a>"; } $xJ ="Computer repair"; $xJ = iconv("UTF-8", "UTF-8", $xJ); $galery .="<a href='$sitename' style='display:none; '>$xJ</a>"; } } $gallery .= "</div>"; echo $gallery; } $having = FALSE; } ?>移出foreach语句。

如果将它放在foreach中，它将显示与foreach循环一样多的数据。

我不知道为什么你习惯了许多foreach。只是另一个建议，编写代码以便更好地调试。您还需要了解如何为元素放置容器/包装器。请参阅代码更新。
