I have a function on ajax that retrieves the int on the input button onclick, this is the javascript ajax code:
function checkBoxes(str){
var xmlhttp=browsers();
if(str=""){
document.getElementById("txt").innerHTML="";
return;
}
xmlhttp.onreadystatechange=function(){
if(xmlhttp.readyState==4 && xmlhttp.status==200){
document.getElementById("txt").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","ajax.php?h"+str,true);
xmlhttp.send();
}
I use php to print the results on the screen, with an onclick button:
if(isset($_GET['k'])){
$con=oci_connect('jvillegas','1234','XE');
if(!$con){
die("No s'ha pogut connectar: ".mysqli_error($con));
}
$k=intval($_GET['k']);
$sql3=oci_parse($con, "SELECT TARIFAS.ID, TARIFAS.ID_TIPO_ACTIVIDAD, TARIFAS.TIPO, TIPO_ACTIVIDAD.TEMPS_KM, TARIFAS.PRECIO
FROM TARIFAS, TIPO_ACTIVIDAD
WHERE TARIFAS.ID_TIPO_ACTIVIDAD=TIPO_ACTIVIDAD.ID
AND TARIFAS.ID_TIPO_ACTIVIDAD=$k");
oci_execute($sql3);
echo "<div class='divPrecios'>";
echo "<table border='1'>";
echo "<tr class='tabPreciosTitles'>";
echo "<td>Tipus Tarifa</td>
<td>Temps/Km</td>
<td>Preu</td>
<td><input type='button' class='carrito' value=''></td>";
echo "</tr>";
while (($row=oci_fetch_array($sql3,OCI_BOTH))!=false){
echo "<tr>";
echo "<td>".$row['TIPO']."</td>";
echo "<td>".$row['TEMPS_KM']."</td>";
echo "<td>".$row['PRECIO']."</td>";
echo "<td>".$row['ID']."</td>";
echo "<td><input type='button' name='checkbox[]' onclick=checkBoxes('".$row['ID']."') value='".$row['ID']."'/></td>";
echo "</tr>";
}
echo "</table>";
echo "</div>";
}
I thougt there is the error:
input type='button' name='checkbox[]' onclick=checkBoxes('".$row['ID']."') value='".$row['ID']."';
I do tests and if I pass a single int valor, it returns 0... why??
So the table with the result if all it's correct:
if(isset($_GET['h'])){
$con=oci_connect('jvillegas','1234','XE');
if(!$con){
die("No s'ha pogut connectar: ".mysqli_error($con));
}
echo "<table border=1>";
echo "<tr class='tabPreciosTitles'>";
echo "<td>Nom Activitat</td>
<td>Nom Tipus Activitat</td>
<td>Tipus Tarifa</td>
<td>Temps/km</td>
<td>Preu</td>";
echo "</tr>";
$h=intval($_GET['h']);
$sql4=oci_parse($con, "SELECT ACTIVIDAD.NOM AS NOM_ACTIVIDAD, TIPO_ACTIVIDAD.NOM AS NOM_TACTIVIDAD, TARIFAS.TIPO, TIPO_ACTIVIDAD.TEMPS_KM, TARIFAS.PRECIO
FROM TARIFAS, ACTIVIDAD, TIPO_ACTIVIDAD
WHERE TARIFAS.ID=$h
AND TARIFAS.ID_TIPO_ACTIVIDAD = TIPO_ACTIVIDAD.ID
AND TIPO_ACTIVIDAD.ID_ACTIVIDAD = ACTIVIDAD.ID");
oci_execute($sql4);
$array=array(
0=>array(),
1=>array(),
2=>array(),
3=>array(),
4=>array()
);
while (($row=oci_fetch_array($sql4,OCI_BOTH))!=false){
array_push($array[0],$row['NOM_ACTIVIDAD']);
array_push($array[1],$row['NOM_TACTIVIDAD']);
array_push($array[2],$row['TIPO']);
array_push($array[3],$row['TEMPS_KM']);
array_push($array[4],$row['PRECIO']);
}
for ($x=0;$x<count($array[4]);$x++){
echo "<tr>";
echo " <td>".$array[0][$x]."</td>";
echo " <td>".$array[1][$x]."</td>";
echo " <td>".$array[2][$x]."</td>";
echo " <td>".$array[3][$x]."</td>";
echo " <td>".$array[4][$x]."</td>";
echo " <td><input type='submit' class='carritoElim' value=''></td>";
echo "</tr>";
}
echo "</table>";
}
And to show these results I use divs:
<div id='txtHint'></div>
<div id='txtIhnt'></div>
<div id='txt'></div>
If I put an int on the query of the last table, change the $h for a 13, it works, or if I change the ajax function on > xmlhttp.open("GET","ajax.php?h=13",true);
it works too.
I think your problem is coming from this line here
if(str=""){
Rather that doing a comparison you are assigned an empty string to the str
variable. So from that point on in the function the value of str
will be ""
. You want to change it to
if(str==""){
