在另一位编码员的帮助下,我有 PHP 代码可以创建一个照片库,其中包含目录中任何图像文件的自动创建的缩略图。(它是开源的,因此其他任何人都可以随意使用和修改。)
我将它用作库存照片库,文件名包括该图像的关键字。例如,可能是businessman-tie-suit-briefcase-office-meeting.jpg。
我一直在尝试添加查看文件名的关键字搜索输入,但无法弄清楚如何继续。我已经为数据库构建了关键字搜索,但是这个目录文件名搜索对我来说是新的。
这是页面的相关代码:
<?
$gallery = $_GET["gallery"];
$dir = $dir.$gallery."/";
//Put files into an array
// create a handler to the directory
$dirhandler = opendir($dir);
// read all the files from directory
$nofiles=0;
while ($file = readdir($dirhandler)) {
// if $file isn't this directory or its parent
//add to the $files array
if ($file != '.' && $file != '..')
{
$nofiles++;
$files[$nofiles]=$file;
}
}
//close the handler
closedir($dirhandler);
//Back button to appear at the top of each page to go to the previous directory if not on the main page
if ($gallery !="" or $keyword !="")
{
echo "<div><a href='javascript:history.go(-1)'><img src='images/up.png' border='0'></a></div>";
}
// BEGINNING ADD FOR KEYWORD SEARCH
// KEYWORD SEARCH BOX- create text box to search entire directory for that keyword and display page in grid pattern with results
?>
<div style='position:relative; left:10px;'>
<form action='index_search.php?keyword=$keyword' method='get' name='search'>
<input type='text' name='keyword' size='25'>
<input type='submit' value='Search Keyword'>
</form>
</div>
<?
//*************************************************************************//
// PERFORM KEYWORD SEARCH
if ($keyword !="")
{
echo "<div class='keytext'>Keyword search: <b>" . $keyword . "</b><br/></div>";
/*********************************************************************************************************/
/* ***** THIS IS WHERE THE SEARCH OF DIRECTORY FILES NEEDS TO OCCUR AND OUTPUT RESULTS AS $files */
/* get results where $file LIKE %$keyword%; */
/*********************************************************************************************************/
//Show images
foreach ($files as $file)
{
if ($file!="."&&$file!="..")
{
$extention = explode('.', $file);
if ($extention[1] != "")
{
echo "<div class='imgwrapper'>";
echo"<a class='fancybox' rel='group'' href='$dir$file' return false' title='$filename'>";
echo "<img src='timthumb.php?src=$dir$file&h=$height&w=$width' alt='$extention[0]' width='$width' height='$height'/>";
echo"</a><br/>";
$file_name = current(explode('.', $file));
echo substr($file_name,0,21);
echo "</div>";
}
}
}
}
else { // starts the split from keyword or no keyword
//***********************************************************************//
// sort folder names alphabetically, ignore case
natcasesort($files);
//Show the folders
foreach ($files as $file){
if ($file!="."&&$file!="..")
{
sort($files); //Sorts the array (file names) alphabetically -- not the directory/folder names
$extention = explode('.', $file);
if ($extention[1] == "")
{
echo "<div class='imgwrapper'>";
echo "<a href='?gallery=$gallery/$file'>";
echo "<img src='images/folder.jpg' border='0'>";
echo "<div class='folder'>";
echo current(explode('.', $file));
echo "</a>";
echo "</div>";
echo "</div>";
}
}
}
?>
<div style="clear:both"></div>
<?
//Show images
foreach ($files as $file){
if ($file!="."&&$file!="..")
{
$extention = explode('.', $file);
if ($extention[1] != "")
{
echo "<div class='imgwrapper'>";
echo"<a class='fancybox' rel='group'' href='$dir$file' return false' title='$filename'>";
echo "<img src='timthumb.php?src=$dir$file&h=$height&w=$width' alt='$extention[0]' width='$width' height='$height'/>";
echo"</a><br/>";
echo "<div class='title'>";
$file_name = current(explode('.', $file));
echo substr($file_name,0,125);
echo "</div>";
echo "</div>";
}
}
}
}
?>
我已将我认为将执行搜索字符串的区域注释掉,因为显示代码已经存在。我已经尝试了一些不起作用的东西,所以没有费心列出任何东西。
如果我以错误的方式解决这个问题,有什么想法吗?
提前致谢。
