[英]Edit data from table with javascript and php from ajax
I am a beginner in PHP and Javascript I used a live editable table and I am trying to edit them and then save them to mysql in another page I did like this, but I didn't know how to retrieve where to edit in mysql with the id
could some one help please! 我是PHP和Javascript的初学者,我使用了一个实时可编辑表,然后尝试对其进行编辑,然后将它们保存到另一页中的mysql中,我这样做,但是我不知道如何使用该
id
可以帮上忙! Am i wrong in the request? 我的要求错了吗? it doesn't change in the database like it does in the table in the page.
它在数据库中不会像在页面中的表中那样发生变化。 I sent the data like this:
我发送了这样的数据:
function postedit()
{
var _type = $('#typeid').val();
var _pression = $('#pressionid').val();
var _code = $('input[name="code"]').val();
var _designiation = $('input[name="designiation"]').val();
var _diametre = $('input[name="diametre"]').val();
var _epaisseur = $('input[name="epaisseur"]').val();
var _prix = $('input[name="prix"]').val();
var _etat = $('input[name="etat"]').val();
$.post('update.php', {
posttype: _type,
postpression: _pression,
postcode: _code,
postdesigniation: _designiation,
postdiametre: _diametre,
postepaisseur: _epaisseur,
postprix:_prix,
postetat:_etat
},
function(data){
$('tbody').append(data);
});
}
var _trEdit = null;
$(document).on('click', '.btn-edit',function(){
_trEdit = $(this).closest('tr');
var _code = $(_trEdit).find('td:eq(0)').text();
var _designiation = $(_trEdit).find('td:eq(1)').text();
var _diametre = $(_trEdit).find('td:eq(2)').text();
var _epaisseur = $(_trEdit).find('td:eq(3)').text();
var _prix = $(_trEdit).find('td:eq(4)').text();
var _etat = $(_trEdit).find('td:eq(5)').text();
$('input[name="code"]').val(_code);
$('input[name="designiation"]').val(_designiation);
$('input[name="diametre"]').val(_diametre);
$('input[name="epaisseur"]').val(_epaisseur);
$('input[name="prix"]').val(_prix);
$('input[name="etat"]').val(_etat);
});
$('#btn-update').click(function(){
if(_trEdit){
var _code = $('input[name="code"]').val();
var _designiation = $('input[name="designiation"]').val();
var _diametre = $('input[name="diametre"]').val();
var _epaisseur = $('input[name="epaisseur"]').val();
var _prix = $('input[name="prix"]').val();
var _etat = $('input[name="etat"]').val();
$(_trEdit).find('td:eq(0)').text(_code);
$(_trEdit).find('td:eq(1)').text(_designiation);
$(_trEdit).find('td:eq(2)').text(_diametre);
$(_trEdit).find('td:eq(3)').text(_epaisseur);
$(_trEdit).find('td:eq(4)').text(_prix);
$(_trEdit).find('td:eq(5)').text(_etat);
alert("Ligne Modifier avec succée !");
_trEdit = null;
}
});
My sql request in a file update.php
like this I thought that if I get the id
from the database and search from it, it seems stupid but I am desperate: 我在这样的文件
update.php
sql请求,我认为如果我从数据库中获取id
并从中搜索,这似乎很愚蠢,但我很绝望:
$type_utilisation = $_POST['posttype'];
$pression_tube = $_POST['postpression'];
$code_tube = $_POST['postcode'];
$designiation_tube = $_POST['postdesigniation'];
$diametre_tube = $_POST['postdiametre'];
$epaisseur_tube = $_POST['postepaisseur'];
$prix_tube = $_POST['postprix'];
$etat_tube = $_POST['postetat'];
$id_req = ("select id from $pression_tube where typepehd='".$type_utilisation."' && code='".$code_tube."'");
$id_tube=$id_req;
echo"$id_tube";
if(isset($pression_tube)){
if($pression_tube=="pn4"){
if($type_utilisation=="pehdtelecom" && $pression_tube=="pn4" ){
echo "verifier le type du Tube S.v.p";
} else {
$sql="UPDATE pn4 SET typepehd='".$type_utilisation."',code='".$code_tube."',designiation='".$designiation_tube."',diametre='".$diametre_tube."',epaisseur='".$epaisseur_tube."',prix='".$prix_tube."',etat='".$etat_tube."' where id='".$id_tube."'";
$result = mysqli_query($link, $sql);
if($result){
} else {
echo "ERROR: Could not able to execute $sql. " . mysqli_error($link);
}
}
}
thank you, i did solve it by using the id because its unique 谢谢,我确实通过使用id来解决它,因为它的唯一性
$id_tube = $_POST['postid'];
by adding an input to it in type hidden and make the column invisible by 通过向其添加隐藏类型的输入,并使该列不可见
