所以我第一次在项目中使用AJAX，我试图发送一个POST但我认为我没有发送请求的权利，或者有我的语法错误或加价。它必须是基本的东西，因为我得到了一些要求。检查出this test domain。任何人都可以对这些PHP错误如何进入它有任何意义？AJAX不检索所有数据与JavaScript请求
这里是我的加价文件：

这是我的“work.php”的AJAX与来自最后一个文档的work_year输入请求：
<?php
require("opendbas3.php");
$work_year = $_POST["work_year"];
$w_query = "SELECT * FROM kb_work WHERE p_date='$work_year' ORDER BY p_id DESC";
$w_result = mysql_query($w_query, $link);
while ($w_row = mysql_fetch_array($w_result)) {
$w_id = array(); $w_id_str = $w_row["p_id"]; array_push($w_id, $w_id_str);
$w_src = array(); $w_src_str = $w_row["p_src"]; array_push($w_src, $w_src_str);
$w_title = array(); $w_title_str = $w_row["p_title"]; array_push($w_title, $w_title_str);
$w_medium = array(); $w_medium_str = $w_row["p_medium"]; array_push($w_medium, $w_medium_str);
$w_size = array(); $w_size_str = $w_row["p_size"]; array_push($w_size, $w_size_str);
$w_date = array(); $w_date_str = $w_row["p_date"]; array_push($w_date, $w_date_str);
}
print('<div id="gallery-control-bar">');
print('<div id="gallery-buttons" class="control-bar-item">');
print('<div id="previous-button" class="gallery-button">←</div>');
print('<div id="next-button" class="gallery-button">→</div>');
print('</div><!-- "#gallery-buttons" -->');
print('<div id="image-index" class="control-bar-item"><span id="current-post"></span> of <span id="post-total"></span></div>');
print('<div id="gallery-type" class="control-bar-item">');
print('<img id="gallery-switch" alt="Kyle Breitenbach Art Gallery Icon" src="images/gallery-icon.png"');
print('</div><!-- "#gallery-type -->');
print('</div><!-- "#gallery-control-bar" -->');
print('<div id="gallery-image"></div>');
print("<div id='gallery-viewer'>");
foreach($w_id as $key => $value) {
print("<div class='gallery-row'>");
$i = 1;
for ($x = 0; $x < sizeof($w_id); $x++) {
print("<img id='" . $x . "' class='gallery-item' src='" . $w_src[$x] . "' alt='Kyle Breitenbach " . $w_title[$x] . "'>");
if (($i % 4) == 0) {
print("</div><div class='gallery-row'>");
}
$i++;
}
print("</div>");

print("var w_id = " . json_encode($w_id));

print("var w_date = " . json_encode($w_date));
print("</script>");
?>
这是将这些效果结合在一起的JS文件，这个东西可能有点不相关：
var currentImg = 0;
var totalImg = 0;
$("#next-button").click(function() {
if (currentImg == totalImg) {
currentImg = 0;
}
else {
currentImg++;
}
changeImg();
});
$("#previous-button").click(function() {
if (currentImg == 0) {
currentImg = totalImg;
}
else {
currentImg--;
}
changeImg();
});
function changeImg() {
$("#gallery-image").html("<img src='" + w_src[currentImg] + "'>");
$("#gallery-title").html(w_title[currentImg]);
$("#gallery-medium").html(w_medium[currentImg]);
$("#gallery-size").html(w_size[currentImg]);
$("#gallery-date").html(w_date[currentImg]);
var userCurrent = currentImg + 1;
var userTotal = galleryYear.x_id.length;
$("#current-post").html(userCurrent);
$("#post-total").html(userTotal);
var galWidth = $("#gallery-image" > "img").width();
$("#gallery").width(galWidth);
}
你有什么想法可以重新接近AJAX，也许有不同的调用函数的配置吗？也许有些东西会更适合我的请求的性质，使其正常工作？
提供AJAX结果**的脚本不应该格式化任何东西，它应该返回一个很好的数据集，然后请求者将对其进行格式化。你应该重新评估它的工作方式。 –
从错误中看来，$ w_date是未定义的。尝试为此设置一个硬性值，看看它是否纠正了它。如果确实如此，找出你的var为什么没有定义。 – Mattt
