我想知道将“$ imagepath”写入此输入的最佳方法
这是我的上传脚本
<?php
if(isset($_POST['submit'])){
if (isset ($_FILES['new_image'])){
$imagename = $_FILES['new_image']['name'];
$source = $_FILES['new_image']['tmp_name'];
$target = "temporary_images/".$imagename;
move_uploaded_file($source, $target);
$imagepath = $imagename;
$save = "temporary_images/" . $imagepath; //This is the new file you saving
$file = "temporary_images/" . $imagepath; //This is the original file
list($width, $height) = getimagesize($file) ;
$modwidth = 350;
$modheight = 100;
$tn = imagecreatetruecolor($modwidth, $modheight) ;
$image = imagecreatefromjpeg($file) ;
imagecopyresampled($tn, $image, 0, 0, 0, 0, $modwidth, $modheight, $width, $height) ;
imagejpeg($tn, $save, 100) ;
$save = "temporary_images/sml_" . $imagepath; //This is the new file you saving
$file = "temporary_images/" . $imagepath; //This is the original file
list($width, $height) = getimagesize($file) ;
$modwidth = 80;
$modheight = 100;
$tn = imagecreatetruecolor($modwidth, $modheight) ;
$image = imagecreatefromjpeg($file) ;
imagecopyresampled($tn, $image, 0, 0, 0, 0, $modwidth, $modheight, $width, $height) ;
imagejpeg($tn, $save, 100) ;
echo "Large image: <img src='temporary_images/".$imagepath."'><br>";
echo "$imagepath"
}
}
这是我的表格
<form>
<input name="animeinput" id="animeinput" size="20" class="textbox">
</form>

如果你有可用于标记的var:
<form>
<input name="animeinput" id="animeinput" size="20" class="textbox" value="<?php echo htmlspecialchars($imagePath); ?>" />
</form>

请注意,执行此操作时,通常会出现缓存和计时问题(因此,如果您在提交表单后遇到问题时遇到问题,请参阅下文),我想这与图像不存在有关在加载结果页面时到位。我通过使用jquery / ajax更新我的图像解决了这个问题。
发布表单并上传图片后,我会在隐藏标签#large_image中保存对图片的引用。然后使用这个jquery ....
$(document).ready(function(){
//read in hidden reference to image URL
var large_photo = $("#large_image").val();
//display relevent image (use placeholder if no image uploaded yet)
if (large_photo != "") {
$("#photo_holder").html('<img src="' + large_photo + '" />');
} else {
$("#photo_holder").html('<img src="noimagefound.png" />');
}
});
在你的情况下,不是回显图像src,而是回显一个带有图像路径的隐藏标签。
希望这会有所帮助:)
