PHP MYSQL 分页列出所有字段

Question

您好，我目前正在尝试为我正在构建的博客构建一些分页。该脚本工作正常，但它只显示博客文章标题的列表，但我希望它显示表中所有字段的列表。

我猜是这个……

// get the info from the db
$sql = "SELECT blog_heading number FROM `Blog Posts` LIMIT $offset, $rowsperpage";

$result = mysql_query($sql, $conn) or trigger_error("SQL", E_USER_ERROR);

// while there are rows to be fetched...
while ($list = mysql_fetch_assoc($result)) {
   // echo data
   echo $list['number'] . "<br />";
} // end while

我已经厌倦了在选择中添加倍数（用逗号分隔），它只显示最近选择的字段。

这里是完整的代码...

<?php
// database connection info
$conn = mysql_connect("...", "...", "...", '...') or trigger_error("SQL", E_USER_ERROR);
$db = mysql_select_db('...',$conn) or trigger_error("SQL", E_USER_ERROR);

// find out how many rows are in the table
$sql = "SELECT COUNT(*) FROM `Blog Posts`";
$result = mysql_query($sql, $conn) or trigger_error("SQL", E_USER_ERROR);
$r = mysql_fetch_row($result);
$numrows = $r[0];

// number of rows to show per page
$rowsperpage = 10;
// find out total pages
$totalpages = ceil($numrows / $rowsperpage);

// get the current page or set a default
if (isset($_GET['currentpage']) && is_numeric($_GET['currentpage'])) {
   // cast var as int
   $currentpage = (int) $_GET['currentpage'];
} else {
   // default page num
   $currentpage = 1;
} // end if

// if current page is greater than total pages...
if ($currentpage > $totalpages) {
   // set current page to last page
   $currentpage = $totalpages;
} // end if
// if current page is less than first page...
if ($currentpage < 1) {
   // set current page to first page
   $currentpage = 1;
} // end if

// the offset of the list, based on current page
$offset = ($currentpage - 1) * $rowsperpage;

// get the info from the db
$sql = "SELECT blog_heading number FROM `Blog Posts` LIMIT $offset, $rowsperpage";

$result = mysql_query($sql, $conn) or trigger_error("SQL", E_USER_ERROR);

// while there are rows to be fetched...
while ($list = mysql_fetch_assoc($result)) {
   // echo data
   echo $list['number'] . "<br />";
} // end while

/******  build the pagination links ******/
// range of num links to show
$range = 3;

// if not on page 1, don't show back links
if ($currentpage > 1) {
   // show << link to go back to page 1
   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=1'><<</a> ";
   // get previous page num
   $prevpage = $currentpage - 1;
   // show < link to go back to 1 page
   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$prevpage'><</a> ";
} // end if 

// loop to show links to range of pages around current page
for ($x = ($currentpage - $range); $x < (($currentpage + $range) + 1); $x++) {
   // if it's a valid page number...
   if (($x > 0) && ($x <= $totalpages)) {
      // if we're on current page...
      if ($x == $currentpage) {
         // 'highlight' it but don't make a link
         echo " [<b>$x</b>] ";
      // if not current page...
      } else {
         // make it a link
         echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$x'>$x</a> ";
      } // end else
   } // end if
} // end for

// if not on last page, show forward and last page links        
if ($currentpage != $totalpages) {
   // get next page
   $nextpage = $currentpage + 1;
    // echo forward link for next page
   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$nextpage'>></a> ";
   // echo forward link for lastpage
   echo " <a href='{$_SERVER['PHP_SELF']}?currentpage=$totalpages'>>></a> ";
} // end if
/****** end build pagination links ******/
?>

谢谢

您需要从博客文章中选择所有内容，以便用所有内容填充结果

SELECT * FROM `Blog Posts` LIMIT $offset, $rowsperpage";

在最后 2 个回显中，您的 a 链接是空白的，因此您将无法看到要点击的链接
